 content is relatively stable. Breast milk is made from nutrients in the mother's bloodstream and bodily stores. Because breastfeeding uses an average of 500 calories a day it helps the mother lose weight after giving birth. The composition of breast milk changes depending on how long the baby nurses at each session, as well as on the age of the child.

Research shows that the milk and energy content of breastmilk actually decreases after the first year. Breastmilk adapts to a toddler's developing system, providing exactly the right amount of nutrition at exactly the right time. In fact, research shows that between the ages of 12 and 24 months, 448 milliliters of human milk provide these percentages of the following minimum daily requirements:
Energy: 29%
Folate: 76%
Protein: 43%
Vitamin B12: 94%
Calcium: 36%
Vitamin C: 60%
Vitamin A: 75%


The quality of a mother's breast milk may be compromised by stress, bad food habits, chronic illnesses, smoking, and drinking.

Breastfeeding releases oxytocin

, hormones that relax the mother and make her feel more nurturing toward her baby. Breastfeeding soon after giving birth increases the mother's oxytocin levels, making her uterus contract more quickly and reducing bleeding. Oxytocin is similar to pitocin, a synthetic hormone used to make the uterus contract.

Weight loss

As the fat accumulated during pregnancy is used to produce milk, extended breastfeeding—at least 6 months—can help mothers lose weight. However, weight loss is highly variable among lactating women, and diet and exercise are more reliable ways of losing weight.

Natural postpartum infertility


A fully breastfeeding woman may not ovulate, or have regular periods, for up to 6 months. This Lactational amenorrhea, should not be relied on as a form of contraception.

Organisational endorsements

The WHO recommends at least two years of breastfeeding and exclusive breastfeeding for the first six months of life. Breastfeeding should continue after two years of life as long as mutually desired by mother and child.

American Academy of Pediatrics


AAP recommends at least one year of breastfeeding and exclusive breastfeeding for the first six months of life. Breastfeeding should continue after two years of life as long as mutually desired by mother and child.

Breastfeeding difficulties

While breastfeeding is a natural human activity, difficulties are not uncommon. Putting the baby to the breast as soon as possible after the birth helps to avoid many problems. The AAP breastfeeding policy says:
Delay weighing, measuring, bathing, needle-sticks, and eye prophylaxis until after the first feeding is completed. Many breastfeeding difficulties can be resolved with proper hospital procedures, properly trained midwives, doctors and hospital staff, and lactation consultants. There are some situations in which breastfeeding may be harmful to the infant, including infection with HIV
HIV

Human immunodeficiency virus is a lentivirus that can lead to AIDS , a condition in humans in which the immune system begins to fail, leading to life-threatening opportunistic infections....
 and acute poisoning by environmental contaminants such as lead. Rarely, a mother may not be able to produce breastmilk because of a prolactin deficiency. This may be caused by Sheehan's syndrome, an uncommon result of a sudden drop in blood pressure during childbirth typically due to hemorrhaging. In developed countries, many working mothers do not breast feed their children due to work pressures. For example, a mother may need to schedule for frequent pumping breaks, and find a clean, private and quiet place at work for pumping. These inconveniences may cause mothers to give up on breast feeding and use infant formula instead.

Infant weight gain


Breastfed infants generally gain weight according to the following guidelines:

0–4 months: 170 grams per week
4–6 months: 113–142 grams per week
6–12 months: 57–113 grams per week


It is acceptable for some babies to gain 113–142 grams (4–5 ounces) per week. This average is taken from the lowest weight, not the birth weight.


The average breastfed baby doubles its birth weight in 5–6 months. By one year, a typical breastfed baby will weigh about 2½ times its birth weight. At one year, breastfed babies tend to be leaner than bottle fed babies. By two years, differences in weight gain and growth between breastfed and formula-fed babies are no longer evident.;

s in hospitals or private practice, and volunteer organisations of breastfeeding mothers such as La Leche League also provide advice and support.

Early breastfeeding

In the half hour after birth, the baby's suckling reflex is strongest, and the baby is more alert, so it is the ideal time to start breastfeeding. . Early breast-feeding is associated with fewer nighttime feeding problems

Time and place for breastfeeding

Breastfeeding at least every two to three hours helps to maintain milk production. For most women, eight breastfeeding or pumping sessions every 24 hours keeps their milk production high. Newborn babies may feed more often than this: 10 to 12 breastfeeding sessions every 24 hours is common, and some may even feed 18 times a day. Feeding a baby "on demand" (sometimes referred to as "on cue"), means feeding when the baby shows signs of hunger
Hunger

Hunger is a feeling experienced when one has a desire to eat. The often unpleasant feeling originates in the hypothalamus and is released through receptors in the liver....
; feeding this way rather than by the clock helps to maintain milk production and ensure the baby's needs for milk and comfort are being met. However, it may be important to recognize whether a baby is truly hungry, as breastfeeding too frequently may mean the child receives a disproportionately high amount of foremilk, and not enough hindmilk..

"Experienced breastfeeding mothers learn that the sucking patterns and needs of babies vary. While some infants' sucking needs are met primarily during feedings, other babies may need additional sucking at the breast soon after a feeding even though they are not really hungry. Babies may also nurse when they are lonely, frightened or in pain."

"Comforting and meeting sucking needs at the breast is nature's original design. Pacifiers (dummies, soothers) are literally a substitute for the mother when she can't be available. Other reasons to pacify a baby primarily at the breast include superior oral-facial development, prolonged lactational amenorrhea, avoidance of nipple confusion and stimulation of an adequate milk supply to ensure higher rates of breastfeeding success."

Most US states now have laws that allow a mother to breastfeed her baby anywhere she is allowed to be. In hospitals, rooming-in care permits the baby to stay with the mother and improves the ease of breastfeeding. Some commercial establishments provide breastfeeding rooms, although laws generally specify that mothers may breastfeed anywhere, without requiring them to go to a special area.

Latching on, feeding and positioning


Correct positioning and technique for latching on can prevent nipple soreness and allow the baby to obtain enough milk. The "rooting reflex" is the baby's natural tendency to turn towards the breast with the mouth open wide; mothers sometimes make use of this by gently stroking the baby's cheek or lips with their nipple in order to induce the baby to move into position for a breastfeeding session, then quickly moving baby onto the breast while baby's mouth is wide open. In order to prevent nipple soreness and allow the baby to get enough milk, a large part of the breast and areola need to enter the baby's mouth. To help the baby latch on well, tickle the baby's top lip with the nipple, wait until the baby's mouth opens wide, then bring the baby up towards the nipple quickly, so that the baby has a mouthful of nipple and areola

 can be massaged so that the baby will have more to latch onto. Resist the temptation to move towards the baby, as this can lead to poor attachment.

Pain in the nipple or breast is linked to incorrect breastfeeding techniques. Failure to latch on is one of the main reasons for ineffective feeding and can lead to infant health concerns. A 2006 study found that inadequate parental education, incorrect breastfeeding techniques, or both were associated with higher rates of preventable hospital admissions in newborns.

The baby may pull away from the nipple after a few minutes or after a much longer period of time. Normal feeds at the breast can last a few sucks (newborns), from 10 to 20 minutes or even longer (on demand). Sometimes, after the finishing of a breast, the mother may offer the other breast.

While most women breastfeed their child in the cradling position, there are many ways to hold the feeding baby. It depends on the mother and child's comfort and the feeding preference of the baby. Some babies prefer one breast to the other, but the mother should offer both breasts at every nursing with her newborn.

When tandem breastfeeding, the mother is unable to move the baby from one breast to another and comfort can be more of an issue. As tandem breastfeeding brings extra strain to the arms, especially as the babies grow, many mothers of twins recommend the use of more supporting pillows.

Exclusive breastfeeding

Exclusive breastfeeding is when an infant receives no other food or drink besides breast milk. National and international guidelines recommend that all infants be breastfed exclusively for the first six months of life. Breastfeeding may continue with the addition of appropriate foods, for two years or more. Exclusive breastfeeding has dramatically reduced infant deaths in developing countries by reducing diarrhea

s. It has also been shown to reduce HIV transmission from mother to child, compared to mixed feeding.

Exclusively breastfed infants feed anywhere from 6 to 14 times a day. Newborns consume from 30 to 90 ml (1 to 3 US fluid ounces). After the age of four weeks, babies consume about 120ml (4 US fluid ounces) per feed. Each baby is different, but as it grows the amount will increase. It is important to recognize the baby's hunger signs. It is assumed that the baby knows how much milk it needs and it is therefore advised that the baby should dictate the number, frequency, and length of each feed. The supply of milk from the breast is determined by the number and length of these feeds or the amount of milk expressed. The birth weight

 of the baby may affect its feeding habits, and mothers may be influenced by what they perceive its requirements to be. For example, a baby born small for gestational age may lead a mother to believe that her child needs to feed more than if it larger; they should, however, go by the demands of the baby rather than what they feel is necessary.

While it can be hard to measure how much food a breastfed baby consumes, babies normally feed to meet their own requirements. Babies that fail to eat enough may exhibit symptoms of failure to thrive

. If necessary, it is possible to estimate feeding from wet and soiled nappies (diapers): 8 wet cloth or 5–6 wet disposable, and 2–5 soiled per 24 hours suggests an acceptable amount of input for newborns older than 5–6 days old. After 2–3 months, stool frequency is a less accurate measure of adequate input as some normal infants may go up to 10 days between stools. Babies can also be weighed before and after feeds.

 for up to ten hours, refrigerated for up to eight days or frozen for up to four to six months. Research suggests that the antioxidant activity in expressed breast milk decreases over time but it still remains at higher levels than in infant formula.

Expressing breast milk can maintain a mother's milk supply when she and her child are apart. If a sick baby is unable to feed, expressed milk can be fed through a nasogastric tube.

Expressed milk can also be used when a mother is having trouble breastfeeding, such as when a newborn causes grazing and bruising. If an older baby bites the nipple, the mother's reaction - a jump and a cry of pain - is usually enough to discourage the child from biting again.

"Exclusively Expressing", "Exclusively pumping" and "EPing" are terms for a mother who feeds her baby exclusively on her breastmilk while not physically breastfeeding. This may arise because her baby is unable or unwilling to latch on to the breast. With good pumping habits, particularly in the first 12 weeks when the milk supply is being established, it is possible to produce enough milk to feed the baby for as long as the mother wishes. Kellymom has a page of links relating to exclusive pumping.

It is generally advised to delay using a bottle to feed expressed breast milk until the baby is 4-6 weeks old and is good at sucking directly from the breast. As sucking from a bottle takes less effort, babies can lose their desire to suck from the breast. This is called
nursing strike or nipple confusion. To avoid this when feeding expressed breast milk (EBM) before 4-6 weeks of age, it is recommended that breast milk be given by other means such as feeding spoons or feeding cups. Also, EBM should be given by someone other than the breastfeeding mother (or wet nurse), so that the baby can learn to associate direct feeding with the mother (or wet nurse) and associate bottle feeding with other people.

Some women donate their expressed breast milk (EBM) to others, either directly or through a milk bank

 and even water, depending on the age of the child. Babies feed differently with artificial teats than from a breast. With the breast, the infant's tongue massages the milk out rather than sucking, and the nipple does not go as far into the mouth; with an artificial teat, an infant will suck harder and the milk may come in more rapidly. Therefore, mixing breastfeeding and bottle-feeding (or using a pacifier

) before the baby is used to feeding from its mother can result in the infant preferring the bottle to the breast. Orthodontic teats, which are generally slightly longer, are closer to the nipple. Some mothers supplement feed with a small syringe or flexible cup to reduce the risk of artificial nipple preference.

s, although women with closely spaced children can and do continue to nurse the older as well as the younger. As the appetite and feeding habits of each baby may not be the same, this could mean feeding each according to their own individual needs, and can also include breastfeeding them together, one on each breast.

, it is a challenge for a mother to organize feeding around the appetites of all the babies. While breasts can respond to the demand and produce large quantities of milk, it is common for women to use alternatives. However, some mothers have been able to breastfeed triplets successfully .

Tandem breastfeeding may also occur when a woman has a baby while breastfeeding an older child. During the late stages of pregnancy the milk will change to colostrum, and some older nurslings will continue to feed even with this change, while others may wean due to the change in taste or drop in supply. Feeding a child while being pregnant with another can also be considered a form of tandem feeding for the nursing mother, as she also provides the nutrition for two.

Extended breastfeeding

Breastfeeding past two years is called
extended breastfeeding or "sustained breastfeeding" by supporters and those outside the U.S. Supporters of extended breastfeeding believe that all the benefits of human milk, nutritional, immunological and emotional, continue for as long as a child nurses. Often the older child will nurse infrequently or sporadically as a way of bonding with the mother.

History of breastfeeding


For hundreds of thousands of years, humans, like all other mammals, fed their young milk. Before the twentieth century, alternatives to breastfeeding were rare. Attempts in 15th century Europe to use cow or goat milk were not very positive. In the 18th century, flour or cereal mixed with broth were introduced as substitutes for breastfeeding, but this did not have a favorable outcome, either. True commercial infant formula

Sociological factors with breastfeeding

Researchers have found several social factors that correlate with differences in initiation, frequency, and duration of breastfeeding practices of mothers. Race, ethnic differences and socioeconomic status and other factors have been shown to affect a mother’s choice whether or not to breastfeed and how long she breastfeeds her child.

  • Education According to Singh, Kogan, and Lee, more mothers with higher education levels correlated with breastfeeding, and these mothers breastfeed for longer.
  • Race and culture Singh et al also found that African American women are less likely than white women of similar socioeconomic status to breastfeed and Hispanic women are more likely to breastfeed. The Center of Disease Control used information from the National Immunization Survey to determine the proportion of Caucasian and African American children that were ever breast fed. They found that 71.5% of Caucasians had breastfed their child while only 50.1% of African Americans had. At six months of age this fell to 53.9% of Caucasian mothers and 43.2% of African American mothers who were still breastfeeding.
  • Income Deborah L. Dee's research found that women and children who qualify for WIC

    , Special Supplemental Nutrition Program for Women, Infants, and Children were among those who were least likely to initiate breastfeeding. Income level can also contribute to women discontinuing breastfeeding early. More highly educated women are more likely to have access to information regarding difficulties with breastfeeding, allowing them to continue breastfeeding through difficulty rather than weaning early. Women in higher status jobs are more likely to have access to a lactation room and suffer less social stigma from having to breastfeed or express breastmilk at work. In addition, women who are unable to take an extended leave from work following the birth of their child are less likely to continue breastfeeding when they return to work.
  • Other factors Other factors they found to have an effect on breastfeeding are “household composition, metropolitan/non-metropolitan residence, parental education, household income or poverty status, neighborhood safety, familial support, maternal physical activity, and household smoking status.”
