Breast milk (sometimes spelled as breastmilk ) or mother's milk is milk produced by the mammary glands in the breast of female humans. Breast milk is the primary source of nutrition for newborn infants , comprising fats, proteins, carbohydrates, and a varying composition of minerals and vitamins. Breast milk also contains substances that help protect an infant against infection and inflammation, such as symbiotic bacteria and other microorganisms and immunoglobulin A , whilst also contributing to the healthy development of the infant's immune system and gut microbiome .
132-520: The Australian Breastfeeding Association ( ABA ) is an Australian organisation interested in the promotion of breastfeeding and protection of nursing mothers. Members of ABA include nursing mothers and their partners as well as health professionals such as doctors, lactation consultants and midwives. ABA was founded in Melbourne, Victoria in 1964 as the Nursing Mothers' Association , with

Breast milk supply augments in response to the baby's demand for milk, and decreases when milk is allowed to remain in the breasts. When considering
660-558: A distinct functionality. The breast milk of diabetic mothers has been shown to have a different composition from that of non-diabetic mothers. It may contain elevated levels of glucose and insulin and decreased polyunsaturated fatty acids. A dose-dependent effect of diabetic breast milk on increasing language delays in infants has also been noted, although doctors recommend that diabetic mothers breastfeed despite this potential risk. Women breastfeeding should consult with their physician regarding substances that can be unwittingly passed to
792-520: A feeling of energy and satiety. The lower risk of child-onset diabetes may be more applicable to infants who were born from diabetic mothers. The reason is that while breastfeeding for at least the first six months of life minimizes the risk of type 1 diabetes from occurring in the infant, inadequate breastfeeding in an infant prenatally exposed to diabetes was associated with a higher risk of the child developing diabetes later. There are arguments that breastfeeding may contribute to protective effects against
924-485: A higher caloric intake than breastfed babies. Breast milk is not sterile and has its own microbiome , but contains as many as 600 different species of various bacteria , including beneficial Bifidobacterium breve , B. adolescentis , B. longum , B. bifidum , and B. dentium , which contribute to colonization of the infant gut. As a result, it can be defined as a probiotic food, depending on how one defines " probiotic ". Breast milk also contains

Male lactation can occur; the production or administration of the hormone prolactin is necessary to induce lactation (see male lactation ). Actual inability to produce enough milk is rare, with studies showing that mothers from malnourished regions still produce amounts of milk of similar quality to that of mothers in developed countries. There are many reasons
1320-405: A mother may not produce enough breast milk . Some of the most common reasons are an improper latch (i.e., the baby does not connect efficiently with the nipple), not nursing or pumping enough to meet supply, certain medications (including estrogen-containing hormonal contraceptives ), illness, and dehydration. A rarer reason is Sheehan's syndrome , also known as postpartum hypopituitarism , which
1452-410: A mother's breastfeeding capability or the volume of milk she will produce. The process of milk production, termed lactogenesis , occurs in 3 stages. The first stage takes place during pregnancy, allowing for the development of the breast and production of colostrum, the thick, early form of milk that is low in volume, but rich in nutrition. The birth of the baby and the placenta triggers the onset of

It is also beneficial to the mother, as it may improve the development of her milk supply and be beneficial for her mental health. Newborn babies usually breastfeed 8 to 12 times every 24 hours, and they typically express hunger cues every one to three hours for the first two to four weeks of their lives. A newborn has
1716-628: A number of benefits to both mother and baby that infant formula lacks. Increased breastfeeding to near-universal levels in low and medium income countries could prevent approximately 820,000 deaths of children under the age of five annually. Breastfeeding decreases the risk of respiratory tract infections , ear infections , sudden infant death syndrome (SIDS) , and diarrhea for the baby, both in developing and developed countries . Other benefits have been proposed to include lower risks of asthma , food allergies , and diabetes . Breastfeeding may also improve cognitive development and decrease
1848-478: A number of factors as described in the Process "Delay in milk 'coming in'" subsection below. Oxytocin , which signals the smooth muscle of the uterus to contract during pregnancy, labor, birth and following delivery, is also involved in the process of breastfeeding. Oxytocin also contracts the smooth muscle layer of band-like cells surrounding the milk ducts and alveoli to s the newly produced milk through
1980-591: A pacifier beginning at birth or after lactation was established did not significantly affect the duration of exclusive and partial breastfeeding up to four months of age. The CDC, however, currently (2022) reports that early use of pacifiers can have a negative outcome on the success of breastfeeding and they suggest that it should be delayed until breastfeeding is firmly established. Ankyloglossia, also called "tongue-tie" may cause shallow latch, poor milk transfer, and other problems with breastfeeding. There are two types of tongue-ties; an anterior tongue-tie occurs when
2112-401: A poor, shallow latch, the infant latches close to or at the nipple, causing the mother intense pain during latching that is relieved with infant release from the breast. While the infant is at the breast, the first indicators of a shallow latch are having the areola be largely visible outside the infant's mouth and a narrow infant mouth angle. Additional signs result from poor positioning when
2244-535: A possibly low milk supply, it is important to consider the difference between "perceived low milk supply" and "true low milk supply". Perceived low milk supply occurs when mothers, for a variety of reasons, believe that they are not making enough milk to feed their infant. These reasons may include fussiness, colic , preference for the bottle as opposed to the breast, long nursing duration, decreased sensation of breast fulness, and even decreased frequency of infant stools. However, in these cases, it important to reassure
2376-493: A process which leads to a first breastfeed. Shortly after birth, the infant relaxes and makes small movements of the arms, shoulders and head. If placed on the mother's abdomen the baby gradually inches towards the breast, called the breast crawl and begins to feed. After feeding, it is normal for a baby to remain latched to the breast while resting. This is sometimes mistaken for lack of appetite. Absent interruptions, all babies follow this process. Rushing, by picking up and moving
2508-629: A restaurant in New York City, have used human breast milk, or at least advocated its use, as a substitute for cow's milk in dairy products and food recipes . An Icecreamist in London's Covent Garden started selling an ice cream named Baby Gaga in February 2011. Each serving cost £14. All the milk was donated by a Mrs Hiley who earned £15 for every 10 ounces and called it a "great recession beater". The ice cream sold out on its first day. Despite

Human milk is noticeably thinner and sweeter than cow's milk. Whole cow's milk contains too little iron , retinol , vitamin E , vitamin C , vitamin D , unsaturated fats or essential fatty acids for human babies. Whole cow's milk also contains too much protein , sodium , potassium , phosphorus and chloride which may put

Because of its diverse population of cells and multifarious functions, researchers have argued that breast milk should be considered a living tissue. Breast milk contains a unique type of sugars, human milk oligosaccharides (HMOs), which were not present in traditional infant formula, however they are increasing added by many manufacturers. HMOs are not digested by
3036-483: A small stomach capacity, approximately 20 ml. The amount of breast milk that is produced is timed to meet the infant's needs in that the first milk, colostrum, is concentrated but produced in only very small amounts, gradually increasing in volume to meet the expanding size of the infant's stomach capacity. Many newborns will typically feed for 10 to 15 minutes on each breast, however feeds may last up to 45 minutes depending on infant wakefulness and efficiency. It

It is rich in protein and antibodies that provide passive immunity to the baby (the baby's immune system is not fully developed at birth). Colostrum also helps the newborn's digestive system to grow and function properly. Colostrum will gradually change to become mature milk. In the first 3–4 days it will appear thin and watery and will taste very sweet; later,

The somatic cells are mainly lactocytes and myoepithelial cells derived from the mother's mammary glands. The stem cells found in human breast milk have been shown to be able to differentiate into a variety of other cells involved in the production of bodily tissues and
3564-579: Is a viable option. In the absence of pasteurized donor milk, commercial formula milk is recommended as a secondary alternative. However, unpasteurized breast milk from a source other than the infant's mother, particularly when shared informally, carries the risk of vertically transmitting bacteria, viruses (such as HIV ), and other microorganisms from the donor to the infant, rendering it an unsafe alternative. Breastfeeding offers health benefits to mother and child even after infancy. These benefits include proper heat production and adipose tissue development,
3696-436: Is about 54 Calories/100mL. The second type of milk is transitional milk, which is produced during the transition from colostrum to mature breast milk. As the breast milk matures over the course to several weeks, the protein content of the milk decreases on average. The caloric content of breastmilk is reflective of the caloric requirements of the infant, increasing steadily after 12 months. The caloric content of breastmilk in

In a February 2015 ABC News article, one former competitive body builder said, "It isn't common, but I've known people who have done this. It's certainly talked about quite a bit on the bodybuilding forums on the Internet." Calling bodybuilders "a strange breed of individuals", he said, "Even if this type of thing

Many of the infection-fighting and immune system related benefits are associated with human milk oligosaccharides . Breastfeeding also provides health benefits for the mother. It assists the uterus in returning to its pre-pregnancy size and reduces post-partum bleeding, through
4092-504: Is associated with prolactin deficiency and may require hormone replacement. The amount of milk produced depends on how often the mother is nursing and/or pumping : the more the mother nurses her baby or pumps, the more milk is produced. It is beneficial to nurse when the baby wants to nurse rather than on a schedule. A Cochrane review came to the conclusion that a greater volume of milk is expressed whilst listening to relaxing audio during breastfeeding, along with warming and massaging of

4224-509: Is defined as "an infant's consumption of human milk with no supplementation of any type (no water, no juice, no nonhuman milk and no foods) except for vitamins, minerals and medications." Supplementation with human donor breastmilk may be indicated in some specific cases, as discussed below. After solids are introduced at around six months of age, continued breastfeeding is recommended. The American Academy of Pediatrics recommends that babies be breastfed at least until 12 months, or longer if both
4356-657: Is desired. Indications for use of donor breastmilk are very closely outlined by the American Academy of Pediatrics (AAP). Due to low availability and high cost of donor breastmilk, the AAP recommends prioritizing the use of the milk for infants born with a weight of less than 1500g (approximately 3lb 5oz), as it is helpful in decreasing rates of the severe intestinal infection, necrotizing enterocolitis , in this population. Effective positioning and technique for latching on are necessary to prevent nipple soreness and allow
4488-414: Is especially beneficial for preterm babies who may initially lack the ability to suck effectively. Using cups to feed expressed breast milk and other supplements results in improved breastfeeding outcomes in terms of both duration and extent, compared with traditional bottle and tube feeding. For mothers unable to produce an adequate supply of breast milk, the use of pasteurized donor human breast milk
4620-410: Is helpful to have an electric, high-grade pump so that all of the milk ducts are stimulated. Galactagogues increase milk supply, although even herbal variants carry risks. Non-pharmaceutical methods should be tried first, such as pumping out the mother's breast milk supply often, warming or massaging the breast, as well as starting milk pumping earlier after the child is born if they cannot drink milk at
4752-413: Is important for parents to recognize the difference between Nutritive and Non-Nutritive Sucking. Nutritive Sucking follows a slow, rhythmic pattern, with 1–2 sucks per swallow. Non-nutritive sucking is a faster-paced sucking pattern with few swallows. This swallow pattern is often observed at the beginning and/or the end of a feed. At the beginning of the feed, this pattern triggers milk letdown, while at
4884-405: Is important to have the mother-infant dyad evaluated by a breastfeeding specialist or pediatrician to determine the true cause of the symptoms and determine the need for supplementation. Often, these symptoms are caused by poor milk transfer at the breast, and can be solved with adjustments to the latch, but occasionally they may be caused by other processes, unrelated to breastfeeding, so evaluation

It is also common for women to experience generally manageable symptoms such as; vaginal dryness, De Quervain syndrome , cramping, mastitis , moderate to severe nipple pain and a general lack of bodily autonomy. These symptoms generally peak at

In terms of what to supplement with, the first choice is always the mother's own breastmilk, save any medical contraindications to its use. The second best option for supplementation is pasteurized human donor milk . Finally, specific formulas may be used for supplementation if maternal or donor breastmilk are not options. One situation where this may be

It has an optimal balance of fat, sugar, water, and protein that is needed for a baby's age appropriate growth and development. That being said, a variety of factors can influence the nutritional makeup of breastmilk, including gestational age, age of infant, maternal age, maternal smoking, and nutritional needs of

This inhibitory effect against the infant contracting HIV is likely due to unspecified factors exclusively present in breast milk of HIV-positive mothers. Most women that do not breastfeed use infant formula , but breast milk donated by volunteers to human milk banks can be obtained by prescription in some countries. In addition, research has shown that women who rely on infant formula could minimize

The World Health Organization (WHO) recommend that breastfeeding begin within the first hour of a baby's birth and continue as the baby wants. Health organizations, including the WHO, recommend breastfeeding exclusively for six months. This means that no other foods or drinks, other than vitamin D , are typically given. The WHO recommends exclusive breastfeeding for

In India , mothers commonly breastfeed for 2 to 3 years. Supplementation is defined as the use of additional milk or fluid products to feed an infant, in addition to breastmilk, during the first 6 months of life. The Academy of Breastfeeding Medicine recommends only supplementing when medically indicated, as opposed to mixing use of formula and breastmilk for reasons that are not necessarily medical indications. Some medical indications for supplementation include low blood sugar, dehydration, excessive weight loss or poor gain, and jaundice in

One way to help the infant achieve a deep latch is to compress the breast tissue into a "U" or "hamburger shape," so that the infant can fit the breast tissue into their mouth. This is done by the mother placing her thumb and fingers in line with the infant's nose and mouth respectively and using this grip to compress the breast tissue. If the newborn seems to need help in latching on,

A greater volume of milk expressed can also be attributed to instances where the mother starts pumping milk sooner, even if the infant is unable to breastfeed. Sodium concentration is higher in hand-expressed milk, when compared with the use of manual and electric pumps, and fat content is higher when the breast has been massaged, in conjunction with listening to relaxing audio. This may be important for low birthweight infants. If pumping, it

The Academy of Breastfeeding Medicine recommends that supplementation only be used when medically indicated and when overseen by a medical professional, such as a pediatrician or family physician, and after consultation with an IBCLC. Without sufficient breast stimulation, supplementation can reduce the mother's milk production, so pumping would be indicated in these cases if continued breastfeeding
9768-469: The chin will be close to the breast, and the forehead and nose should be far from the breast. Another sign of a good latch is the contour of the infant's cheeks; the cheeks should be rounded all the way to the edge of the mouth, rather than dimpled or creased at the edge of the mouth. This is a good indicator of effective suck mechanics. Additionally, in order to achieve a deep latch, the infant's mouth must be open wide, preferably wider than 140 degrees. In

Human milk is considered to be healthier than cow's milk and infant formula when it comes to feeding an infant in
10032-457: The control of progesterone and estrogen. These changes include, but are not limited to, dilation of blood vessels, increased blood flow to the uterus, increased availability of glucose (which subsequently is passed through the placenta to the fetus), and increased skin pigmentation, which results in darkening of the nipples and areola , formation of the linea nigra , and onset of melasma of pregnancy . The third stage of labor describes
10164-420: The development of type 1 diabetes because the alternative of bottle-feeding may expose infants to unhygienic feeding conditions. Though it is almost universally prescribed, in some countries during the 1950s, the practice of breastfeeding went through a period where it was out of vogue and the use of infant formula was considered superior to breast milk. However, it is since universally recognized that there
10296-402: The duct system and out through the nipple. This process is known as the milk ejection reflex , or let-down. Because of oxytocin's dual activity at the breast and the uterus, breastfeeding mothers may also experience uterine cramping at the time of breastfeeding, for the first several days to weeks. Prolactin and oxytocin are vital for establishing milk supply initially, however, once
10428-507: The end of the feed, this may be a signal of the infant tired or becoming relaxed with a slower milk velocity. Numerous health organizations, including, but not limited to, the CDC, WHO, National Health Service, Canadian Pediatric Society, American Academy of Pediatrics, and American Academy of Family Physicians, recommend breastfeeding exclusively for six months following birth, unless medically contraindicated. Exclusive breastfeeding
10560-693: The equivalent of Raynaud Syndrome in the breast, mastitis , plugged ducts, and nipple blebs . Pain caused by a problem deep in the breast may also present with nipple pain due to the paths of nerves in the breast. In addition to the serious nature of many of these causes, nipple pain is a common reason for a mother stopping breastfeeding, so it is important that mothers experiencing nipple pain be evaluated. While milk normally "comes in" by 3 days after birth, there are several reasons this may be delayed. Risk factors for this delay include maternal diabetes , stressful delivery, retained placenta , prolonged labor and birth by C-section . Mothers experiencing
10692-728: The fat content very gradually increases, with the milk becoming fattier and fattier over time. The level of Immunoglobulin A (IgA) in breast milk remains high from day 10 until at least 7.5 months post-partum. Human milk contains 0.8–0.9% protein, 4.5% fat, 7.1% carbohydrates, and 0.2% ash (minerals). Carbohydrates are mainly lactose ; several lactose-based oligosaccharides (also called human milk oligosaccharides ) have been identified as minor components. The fat fraction contains specific triglycerides of palmitic and oleic acid (O-P-O triglycerides), and also lipids with trans bonds (see: trans fat ). The lipids are vaccenic acid , and conjugated linoleic acid (CLA) accounting for up to 6% of
10824-415: The first 12 months of breastfeeding is approximated to be 58-72 Calories/100mL. Comparatively, the caloric content after 48 months is approximately 83-129 Calories/100mL. When a mother has her full milk supply and is feeding her infant, the first milk to be expressed is called the foremilk. Foremilk is typically thinner and less rich in calories. The hindmilk that follows is rich in calories and fat. If
10956-415: The first 6 months of life, followed by continued breastfeeding with appropriate complementary foods for up to 2 years and beyond. Of the 135 million babies born every year, only 42% are breastfed within the first hour of life, only 38% of mothers practice exclusive breastfeeding during the first six months, and 58% of mothers continue breastfeeding up to the age of two years and beyond. Breastfeeding has
11088-525: The first six months of an infant’s life. This period is followed by the incorporation of nutritionally adequate and safe complementary solid foods at six months, a stage when an infant’s nutrient and energy requirements start to surpass what breast milk alone can provide. Continuation of breastfeeding is recommended up to two years of age. This guidance is due to the protective benefits of breast milk, which include less infections such as diarrhea—a protection not afforded by formula milk . Breast milk constitutes
11220-479: The first six months of life, but only under extreme situations do international health organizations support feeding an infant breast milk from a healthy wet nurse rather than that of its biological mother. One reason is that the unregulated breast milk market is fraught with risks, such as drugs of abuse and prescription medications being present in donated breast milk. The transmission of these substances through breast milk can do more harm than good when it comes to
11352-542: The gap between the level of immunity protection and cognitive abilities a breastfed child benefits from versus the degree to which a bottle-fed child benefits from them. This can be done by supplementing formula-fed infants with bovine milk fat globule membranes (MFGM) meant to mimic the positive effects of the MFGMs which are present in human breast milk. Expressed breast milk can be stored . Lipase may cause thawed milk to taste soapy or rancid due to milk fat breakdown. It
11484-413: The health outcomes of the infant recipient. In the United States, the online marketplace for breast milk is largely unregulated and the high premium has encouraged food fraud . Human breast milk may be diluted with other liquids to increase volume including cow’s milk , soy milk , and water , thus undermining its health benefits. A 2015 CBS article cites an editorial led by Dr. Sarah Steele in
11616-471: The human milk fat. The principal proteins are alpha- lactalbumin , lactoferrin (apo-lactoferrin), IgA, lysozyme , and serum albumin . In an acidic environment such as the stomach , alpha-lactalbumin unfolds into a different form and binds oleic acid to form a complex called HAMLET that kills tumor cells. This is thought to contribute to the protection of breastfed babies against cancer. Non-protein nitrogen-containing compounds, making up 25% of
11748-501: The inability to latch on properly is related to ankyloglossia, a simple surgical procedure to clip the frenulum can correct the condition. The Academy of Breastfeeding Medicine and the Australian Dental Association have raised concern over the growing trend of oral tie surgeries, due to evidence for benefit being low-quality, inconsistent, or unsupported. Engorgement is the swelling and stretching of
11880-403: The infant but help to make up the intestinal flora . They act as decoy receptors that block the attachment of disease causing pathogens , which may help to prevent infectious diseases. They also alter immune cell responses, which may benefit the infant. As of 2015 more than a hundred different HMOs have been identified; both the number and composition vary between women and each HMO may have
12012-435: The infant comes toward the breast to latch. If the infant leads with their brow or forehead, they are likely to flex their neck; this mechanism of latching causes the nipple to point down and then hit the hard palate during sucking. From an external view, this manifests as the nose and forehead being close to the breast and the chin far from the breast. This neck flexion also obstructs the normal swallowing mechanism, preventing
12144-454: The infant during breastfeeding. Adverse effects include seizures, tremors, restlessness, and diarrhea. To reduce infant exposure to medications used by the mother, use topical therapy or avoid taking the medication during breastfeeding times when possible. Hormonal products and combined oral contraceptives should be avoided during the early postpartum period as they can interfere with lactation. There are some medications that may stimulate
12276-411: The infant from drinking efficiently. In addition to not being able to swallow properly, this shallow latch prevents the infant from adequately compressing the glandular tissue behind the nipple and stimulating milk flow; thus, they may begin to apply more suction, which manifests externally as cheek dimpling, or sucking their cheeks in. When the baby suckles muscles in the breast squeeze milk towards
12408-1323: The infant to the breast, or interrupting the process, such as removing the baby to weigh him/her, may complicate subsequent feeding. Activities such as weighing, measuring, bathing, needle-sticks, and eye prophylaxis wait until after the first feeding. Children who are born preterm (before 37 weeks), children born in the early term period (37 weeks–38 weeks and 6 days), and children born with low muscular tone, such as those with chromosomal abnormalities like Down syndrome or neurological conditions like Cerebral palsy , may have difficulty in initiating breast feeds immediately after birth. These late preterm (34 weeks –36 weeks and 6 days) and early term (37 weeks–38 weeks and 6 days) infants are at increased risk for both breastfeeding cessation and complications of insufficient milk intake (e.g., dehydration, hypoglycemia, jaundice, and excessive weight loss). They are often expected to feed like term babies, but they have less strength and stamina to feed adequately. By convention, such children are often fed on expressed breast milk or other supplementary feeds through tubes, supplemental nursing systems , bottles, spoons or cups until they develop satisfactory ability to suck and swallow breast milk. Regardless of feeding method chosen, human milk feedings, whether from
12540-407: The infant via breast milk, such as alcohol , viruses ( HIV or HTLV-1 ), or medications. Even though most infants infected with HIV contract the disease from breastfeeding, most infants that are breastfed by their HIV positive mothers never contract the disease. While this paradoxical phenomenon suggests that the risk of HIV transmission between an HIV positive mother and her child via breastfeeding
12672-407: The infant's immune system. Produced during pregnancy and the first days after childbirth, colostrum is easy to digest and has laxative properties that help the infant to pass early stools. This aids in the excretion of excess bilirubin , which helps to prevent jaundice . Colostrum also helps to seal the infants gastrointestinal tract from foreign substances and germs, which may sensitize
12804-413: The infant's mouth should be asymmetric , meaning most of the "bottom" of the areola should be in the infants mouth and much more of the "top" of the areola should be visible. This position is helpful in pointing the nipple toward the roof of the infant's mouth, helping the infant recruit more milk. The baby's lips should be flanged out. The neck should be extended to facilitate swallowing, and as such,
12936-665: The infant. The first type of milk produced is called colostrum . The volume of colostrum produced during each feeding is appropriate for the size of the newborn stomach and is sufficient, calorically, for feeding a newborn during the first few days of life. Produced during pregnancy and the first days after childbirth, colostrum is rich in protein and Vitamins A, B12 and K, which supports infants' growth, brain development, vision, immune systems, red blood cells, and clotting cascade. The breast milk also has long-chain polyunsaturated fatty acids which help with normal retinal and neural development. The caloric content of colostrum
13068-561: The infant; true low milk supply; severe nipple pain unrelieved by interventions; and medical contraindications to breastfeeding, as described below. Supplements can be delivered at the breast through a supplemental nursing system in order to stimulate the production of the mother's own milk and to preserve the breastfeeding relationship. Some parents may desire to supplement proactively if early signs of insufficient intake, such as decreased urination, dry mucous membranes, or persistent signs of hunger, are noticed. If these signs are noticed, it
13200-452: The latch process, the infant should be aligned with their abdomen facing their mother, which can be remembered as "tummy-to-mummy," and with their hips, shoulders and head aligned. This alignment helps to facilitate proper, efficient swallowing mechanics. Latching refers to how the baby fastens onto the breast while feeding. Sebaceous glands called Glands of Montgomery located in the areola secrete an oily fluid that lubricate and protect
13332-434: The likelihood of successful breastfeeding at discharge. Skin-to-skin mother-baby contact should still occur, even if the baby is born by Cesarean surgery. The baby is placed on the mother in the operating room or the recovery area. If the mother is unable to immediately hold the baby a family member can provide skin-to-skin care until the mother is able. According to studies cited by UNICEF , babies naturally follow
13464-438: The milk supply is well established, the volume and content of the milk produced is controlled locally. Although prolactin levels are higher on average among breastfeeding mothers, prolactin levels themselves do not correlate to milk volume. At this stage, production of milk is triggered by milk drainage from the breasts. The only way to maintain milk supply is to drain the breasts frequently. Infrequent or incomplete drainage of
13596-401: The milk will be thicker and creamier. Human milk quenches the baby's thirst and hunger and provides the proteins, sugar, minerals, and antibodies that the baby needs. In the 1980s and 1990s, lactation professionals (De Cleats) used to make a differentiation between foremilk and hindmilk. But this differentiation causes confusion as there are not two types of milk. Instead, as a baby breastfeeds,
13728-1010: The milk's nitrogen, include urea , uric acid , creatine , creatinine , amino acids , and nucleotides . Breast milk has circadian variations; some of the nucleotides are more commonly produced during the night, others during the day. Mother's milk has been shown to supply endocannabinoids (the natural neurotransmitters that cannabis simulates) 2-arachidonoylglycerol , anandamide , oleoylethanolamide , palmitoylethanolamide , N-arachidonoyl glycine , eicosapentaenoyl ethanolamide, docosahexaenoyl ethanolamide, N-palmitoleoyl-ethanolamine, dihomo-γ-linolenoylethanolamine, N-stearoylethanolamine, prostaglandin F2alpha ethanolamides and prostaglandin F2 ethanolamides, Palmitic acid esters of hydroxy-stearic acids (PAHSAs). They may act as an appetite stimulant, but they also regulate appetite so infants do not eat too much. That may be why formula-fed babies have
13860-494: The mother and child wish. The World Health Organization's guidelines recommend "continue[d] frequent, on-demand breastfeeding until two years of age or beyond. Extended breastfeeding means breastfeeding after the age of 12 or 24 months, depending on the source. In Western countries such as the United States , Canada , and Great Britain , extended breastfeeding is relatively uncommon and can provoke criticism. In
13992-656: The mother is not herself deficient in vitamins, breast milk normally supplies her baby's needs, with the exception of Vitamin D. The CDC , National Health Service (UK), Canadian Paediatric Society , the American Academy of Pediatrics , and the American Academy of Family Physicians all agree that breast milk alone does not provide infants with an adequate amount of Vitamin D, thus they advise parents to supplement their infants with 400 IU Vitamin D daily. Providing this quantity of Vitamin D to breastfeeding infants has been shown to reduce rates of Vitamin D insufficiency (defined as 25-OH vitamin D < 50 nmol/L). However, there
14124-496: The mother or a donor, are important in the brain development of premature infants, and the NICU having a standardized protocol for feeding is protective against dangerous gastrointestinal infections ( necrotizing enterocolitis ) in these infants. Frequent breastfeeding and/or small amounts of supplementation may be needed for successful outcomes; breast pumping and/or hand expression is often helpful in providing adequate stimulation to
14256-416: The mother should focus on helping the infant by bringing their chin to the breast first. This facilitates a deep, asymmetric latch, and also helps the infant extend their neck and tilt their forehead back to maintain this deep latch and ease the swallowing process. In a good latch, a large amount of the areola, in addition to the nipple, is in the baby's mouth. The amount of areola visible on either side of
14388-521: The mother supports the baby's head with the opposite hand. The mother may choose a reclining position on her back or side with the baby lying next to her. No matter the position the parent-infant dyad finds most comfortable, there are a few components of every position which will help facilitate a successful latch . One key component is maternal comfort. The mother should be comfortable while breastfeeding, and should have her back, feet, and arms supported with pillows as necessary. Additionally, when starting
14520-457: The mother's breast within an hour of birth, globally, sixty percent of infants are not breastfed within this crucial first hour. Breastfeeding within the first hour of life protects the newborn from acquiring infections and reduces risk of death during the neonatal period. Alternatively, breast milk can be expressed using a breast pump and administered via baby bottle , cup, spoon, supplementation drip system, or nasogastric tube . This method
14652-745: The mother's breasts. Starting to breastfeed may be challenging for mothers of preterm infants, especially those born before 34 weeks, because their breasts may still be developing (in Lactogenesis I, see Breastfeeding Physiology). Additionally, mother–infant separation and the stressful environment of the NICU are also barriers to breastfeeding. Availability of a lactation specialist in the NICU can be helpful for mothers trying to establish their milk supply. Additionally, skin-to-skin (Kangaroo Care) has been shown to be safe and beneficial to both mother and baby. Kangaroo Care stabilizes newborn premature infants' vital signs, such as their heart rate, providing
14784-480: The mother, through her touching and taking care of the baby, comes into contact with pathogens that colonize the baby, and, as a consequence, her body makes the appropriate antibodies and immune cells. At around four months of age, the internal iron supplies of the infant, held in the hepatic cells of the liver, are exhausted. The American Academy of Pediatrics recommends that at this time that an iron supplement should be introduced. Other health organisations such as
14916-706: The national headquarters set up in Hawthorn, Victoria in 1970, and groups established in South Australia and Tasmania in 1971. The ABA had over 10,000 members by 1973. In 2001, NMAA changed its name to Australian Breastfeeding Association. As at 2016, over 350,000 people have been members. The ABA has groups across Australia which hold discussion meetings for mothers. Breastfeeding education seminars are run for expectant parents; community education continues through all levels of education from pre-school to tertiary and members visits mothers in hospital to introduce
15048-403: The nipple during latching. The visible portions of the glands can be seen on the skin's surface as small round bumps. The rooting reflex is the baby's natural tendency to turn towards the breast with the mouth open wide. When preparing to latch, mothers should make use of this reflex by gently stroking the baby's philtrum, the area between the upper lip and the nose, with their nipple to induce
15180-403: The nipple. La Leche League and Toronto Public Health offer several techniques to use during pregnancy or even in the early days following birth that may help to bring a flat or inverted nipple out. The World Health Organization's Ten Steps to Successful Breastfeeding recommends total avoidance of pacifiers for breastfeeding infants. In 2016 a large review of studies reported that the use of
15312-421: The nipples. This is called the let-down reflex. Some women report that they do not experience anything while others report a tingling feeling which is sometimes described as quite strong. The baby may be seen to respond to the beginning of the flow of milk by changing from quick sucks to deep rhythmic swallows. Sometimes the let-down is so strong that the baby splutters and coughs and the mother may need to remove
15444-527: The nursing infant. There is a commercial market for human breast milk, both in the form of a wet nurse service and as a milk product. As a product, breast milk is exchanged by human milk banks , as well as directly between milk donors and customers as mediated by websites on the internet. Human milk banks generally have standardized measures for screening donors and storing the milk, sometimes even offering pasteurization , while milk donors on websites vary in regard to these measures. A study in 2013 came to
15576-403: The nutritional benefits of breastmilk, breast milk also provides enzymes, antibodies, and other substances that support the infant's growth and development. The bioactive makeup of breastmilk also changes based on the needs of the infant; for example, when an infant is recovering from an upper respiratory infection , local signaling allows for increased passage of immune cells and proteins to aid
15708-420: The parent that infant weight gain is absolute proof of adequate milk intake. Thus, if the infant breastfeeding exclusively, and is gaining weight appropriately, then the parent can be reassured that they are producing enough milk. True low milk supply can be either primary (caused by medical conditions or anatomical issues in the mother), secondary (caused by not thoroughly and regularly removing milk from
15840-654: The period between the birth of the baby and the delivery of the placenta, which normally lasts less than 30 minutes. The delivery of the placenta causes an abrupt drop off of placental hormones. This drop, specifically in progesterone, allows prolactin to work effectively at its receptors in the breast, leading to an array of changes over the next several days that allow the milk to "come in"; these changes are known collectively as Lactogenesis II. Colostrum continues to be produced for these next few days, as Lactogenesis II occurs. Milk may "come in" as late as five days after delivery; however, this process may be delayed due to
15972-411: The placenta is delivered. Although traditionally, lactation occurs following pregnancy, lactation may also be induced with hormone therapy and nipple stimulation in the absence of pregnancy. Changes in pregnancy , starting around 16 weeks gestational age , prepare the breast for lactation. These changes, collectively known as Lactogenesis I , are directed by hormones produced by the placenta and
16104-697: The production of breast milk. These medications may be beneficial in cases where women with hypothyroidism may be unable to produce milk. A Cochrane review looked at the drug domperidone (10 mg three times per day) with results showing a significant increase in volume of milk produced over a period of one to two weeks. However, another review concluded little evidence that use of domperidone and metoclopramide to enhance milk supply works. Instead, non-pharmacological approaches such as support and more frequent breastfeeding may be more efficacious. Finally, there are other substances besides medications that may appear in breast milk. Alcohol use during pregnancy carries
16236-432: The production of oxytocin (see Production). Breastfeeding can also reduce the risk of breast cancer later in life. Lactation may also reduce the risk for both mother and infant from both types of diabetes. Lactation may protect the infant from specifically developing Type 2 diabetes, as studies have shown that bioactive ingredients in human breast milk could prevent excess weight gain during childhood via contributing to
16368-530: The risk of obesity in adulthood. Benefits for the mother include less blood loss following delivery , better contraction of the uterus, and a decreased risk of postpartum depression . Breastfeeding delays the return of menstruation , and in very specific circumstances, fertility , a phenomenon known as lactational amenorrhea . Long-term benefits for the mother include decreased risk of breast cancer , cardiovascular disease , diabetes , metabolic syndrome , and rheumatoid arthritis . Breastfeeding
16500-490: The risk of gastrointestinal allergies to food, respiratory allergies to air particles like pollen, and other atopic diseases , such as asthma and eczema . It is recommended for mothers to initiate breastfeeding within the first hour after birth. Uninterrupted skin-to-skin contact and breastfeeding can begin immediately after birth, and should continue for at least one hour after birth. This period of infant-mother interaction, known generally as kangaroo care , or
16632-449: The second stage of milk production, triggering the milk to come in over the next several days. The third stage of milk production occurs gradually over several weeks, and is characterized by a full milk supply that is regulated locally (at the breast), predominately by the infant's demand for food. This differs from the second stage of lactogenesis, which is regulated centrally (in the brain) by hormone feedback loops that naturally occur after
16764-409: The sole source of nutrition for exclusively breastfed newborns, supplying all necessary nutrients for infants up to six months. Beyond this age, breast milk continues to be a source of energy for children up to two years old, providing over half of a child's energy needs up to the age of one and a third of the needs between one and two years of age. Despite the capability of most newborns to latch onto
16896-496: The start of breastfeeding but disappear or become considerately more manageable after the first few weeks. Feedings may last as long as 30–60 minutes each as milk supply develops and the infant learns the Suck-Swallow-Breathe pattern. However, as milk supply increases and the infant becomes more efficient at feeding, the duration of feeds may shorten. Older children may feed less often. When direct breastfeeding

Tammy Frissell-Deppe, a family counsellor specialized in attachment parenting , published a book, titled A Breastfeeding Mother's Secret Recipes , providing a lengthy compilation of detailed food and beverage recipes containing human breast milk. Human breast milk
17160-439: The undercover reporter was told a baby died "every 30 seconds" from formula and "Formula is a little bit like AIDS,". The association launched an internal investigation soon afterwards and in a media statement on 29 August 2012 said the "comments reported in the media are not the view of the association and the counsellor involved has been stood down from all duties". Breastfeeding Breastfeeding , also known as nursing ,
17292-435: Was a lack of support and accurate information about breastfeeding. Doctors and nurses at the time were not trained to handle breastfeeding problems and with the modern nuclear family there were few older women to turn to for advice, so the founding members supported each other, thus creating the model for mother-to-mother support than continues today. The other founders were Glenise Francis, Pat Patterson, Jan Barry (a member of
17424-559: Was insufficient evidence in the most recent Cochrane Review , to determine if this quantity reduced rates of Vitamin D deficiency (defined as 25-OH vitamin D < 30 nmol/L) or rickets . Term infants typically do not need iron supplementation. Delaying clamping of the cord at birth for at least one minute improves the infants' iron status for the first year. When complementary (solid) foods are introduced at about 6 months of age, parents should make sure to choose iron-rich foods to help maintain their children's iron stores. In addition to
