Everything about Breast Feeding totally explained
Breastfeeding is the feeding of an
infant or young
child with
breast milk directly from a woman's
breasts, not from a
baby bottle or other container. Babies have a
sucking reflex that enables them to suck and swallow milk. It is possible for most mothers to nourish their infant (or infants in the case of twins and multiple births) by breastfeeding for the first six months, without the supplement of infant formula milk or solid food.
According to a 2001 WHO report, alternatives to breastfeeding include:
- expressed breast milk from an infant’s own mother
- breast milk from a healthy wet-nurse or a human-milk bank
- a breast-milk substitute fed with a cup, which is a safer method than a feeding bottle and teat
In most situations human
breast milk is the best source of
nourishment for human infants, preventing disease, promoting health and reducing health care costs (
exceptions include if the mother is taking certain
drugs or infected with
tuberculosis or
HIV). Experts disagree about how long to breastfeed to gain the greatest benefit, and the risks of using artificial formulas. In both
developing and
developed countries, artificial feeding is associated with more deaths from
diarrhoea in infants.
The World Health Organization recommends a minimum of two years of breastfeeding and exclusive breastfeeding for the first six months of life. AAP recommends at least one year of breastfeeding and exclusive breastfeeding for the first six months of life. Exclusive breastfeeding for the first six months of life "provides continuing protection against diarrhea and respiratory tract infection" that's more common in babies fed formula.

)The
World Health Organization (WHO) and
American Academy of Pediatrics (AAP) both stress the value of breastfeeding for mothers and children. While recognizing the superiority of breastfeeding, regulating authorities work to make artificial feeding safer when it isn't used. The composition of breast milk depends on how long the baby nurses.
"Research shows that the fat and energy content of breastmilk actually increases after the first year. Breastmilk adapts to a toddler's developing system, providing exactly the right amount of nutrition at exactly the right time. and the
maternal bond can also be strengthened.
Research has demonstrated a variety of benefits to breastfeeding an infant. These include:
Breast Cancer
A study at the University of Wisconsin found that adult women who were breast fed in infancy may have a lower risk of developing breast cancer than their non breast-fed counterparts.
Atopy
In children who are at risk (defined as at least one parent or sibling having
atopy) atopic syndrome can be prevented or delayed through exclusive breastfeeding for four months, though these benefits may not be present after four months of age though the key factor may be the age at which non-breastmilk is introduced rather than duration of breastfeeding.
Atopic dermatitis, the most common form of
eczema, can be reduced through exclusive breastfeeding beyond 12 weeks in individuals with a family history of atopy, but when breastfeeding beyond 12 weeks is combined with other foods incidents of eczema rise irrespective of family history.
Celiac disease
A review of the association between breastfeeding and
celiac disease (CD) concluded that breast feeding while introducing
gluten to the diet reduced the risk of CD. The study was unable to determine if breastfeeding merely delayed symptoms or offerred life-long protection.
Diabetes mellitus
Infants exclusively breastfed have less chance of developing
diabetes mellitus type 1 than peers with a shorter duration of breastfeeding and an earlier exposure to cow milk and solid foods. Breastfeeding also appears to protect against
diabetes mellitus type 2, at least in part due to its effects on the child's weight. compared to formula-fed peers, death rates due to diarrhea in breastfed infants are lower irrespective of
development level of country. and
immunoglobulin A protecting against
microorganisms.
Despite also being a factor in the transmission of
HIV from mother to child, some constituents in breastmilk may be protective of infection. In particular, high levels of certain
polyunsaturated fatty acids in breastmilk (including eicosadienoic,
arachidonic and
gamma-Linolenic acids) are associated with a reduced risk of child infection when nursed by HIV-positive mothers. Arachidonic acid and gamma-linolenic acid may also reduce
viral shedding of the HIV virus in breastmilk.
Breastfeeding doesn't appear to offer protection against
allergies.
Intelligence
Babies with a specific variant of the
FADS2 gene (approximately 90% of all babies) demonstrate an average of 7 points higher IQ if breastfed.
Necrotizing enterocolitis
Necrotizing enterocolitis (NC), found mainly in
premature births, is six to ten times more common in infants fed formula exclusively, and three times more common in infants fed a mixture of breast milk and formula, as compared to exclusive breastfeeding. In infants born at more than 30 weeks, NC was twenty times more common in infants fed exclusively on formula.
Nutrition
Breast milk contains the ideal ratio of the
amino acids
cystine,
methionine, and
taurine to support development of the
central and
peripheral nervous system. Children aged seven and eight years old who were of low
birthweight who were breastfed for more than eight months demonstrated significantly higher
intelligence quotient scores than comparable children breastfed for less time, suggesting breastfeeding offers long-term cognitive benefits in some populations.
Obesity
Breastfeeding appears to reduce the risk of extreme
obesity in children aged 39 to 42 months. The protective effect of breastfeeding against obesity is consistent, though small, across many studies, and appears to increase with the duration of breastfeeding.
Otitis media
The duration of certain types of middle ear infections (
otitis media with effusion, OME) in the first two years of life, is associated with a shorter period of breastfeeding in addition to maternal cigarette smoking and feeding while lying down. A reduced proportion and duration of any
otitis media infection was associated with breastfeeding rather than formula feeding for the first twelve months of life.
Sudden infant death syndrome
Breastfed babies have improved arousal from sleep, which may reduce the risk of
sudden infant death syndrome.
Urinary tract infection
Breastfeeding reduced the risk of acquiring
urinary tract infections in infants up to seven months
post-partum. The protection was strongest immediately after birth, and was ineffective past seven months
Benefits for mothers
Breastfeeding is a cost effective way of feeding an infant, and provides the best nourishment for a child at a small nutrient cost to the mother. Frequent and exclusive breastfeeding can delay the return of fertility through
lactational amenorrhea, though breastfeeding is at best an imperfect means of
birth control. During breastfeeding beneficial
hormones are released into the mother's body.
Breast cancer
Breastfeeding mothers have less risk of
endometrial,
breast and
ovarian cancer, and breastfeeding
diabetic mothers require less insulin. Breastfeeding helps stabilize maternal
endometriosis,
Some breastfeeding women have pain from
candidiasisor
staphylococcus infections of the
nipple though these can be managed with medical attention with little concern for mother and child.
Arthritis
Women who breast feed for longer have a smaller chance of getting rheumatoid arthritis, suggests a Malmo University study published online ahead of print in the Annals of the Rheumatic Diseases (See
Women Who Breast Feed for More than a Year Halve Their Risk of Rheumatoid Arthritis
). The study also found that taking oral contraceptives, which are suspected to protect against the disease because they contain hormones that are raised in pregnancy, didn't have the same effect. Simply having children but not breast feeding also didn't seem to be protective.
Bonding
The hormones released during breastfeeding strengthen the
maternal bond. Teaching partners how to manage common difficulties is associated with higher breastfeeding rates. Support for a mother while breastfeeding can assist in
familial bonds and help build a
paternal bond between father and child.
If the mother is away, an alternative caregiver may be able to feed the baby with expressed breast milk. The various
breast pumps available for sale and rent help working mothers to feed their babies breast milk for as long as they want. To be successful, the mother must produce and store enough milk to feed the child for the time she's away, and the feeding caregiver must be comfortable in handling breast milk.
Hormone release
Breastfeeding releases the hormones
oxytocin and
prolactin which 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 fat accumulated during pregnancy is used to produce milk, breastfeeding can help mothers lose weight.
Organisational endorsements
World Health Organization
The WHO recommends two years of breastfeeding and exclusive breastfeeding for the first six months of life.
American Academy of Pediatrics
Some women donate their expressed breast milk (EBM) to others, either directly or through a
milk bank. Though historically the use of
wet nurses was common, some women dislike the idea of feeding their own child with another woman's milk; others appreciate being able to give their baby the benefits of breast milk. Feeding expressed breast milk—either from donors or the baby's own mother—is the feeding method of choice for premature babies. The transmission of some
viral diseases through breastfeeding can be prevented by expressing breast milk and subjecting it to Holder
pasteurisation.
Mixed feeding
Predominant or mixed breastfeeding means feeding breast milk along with
infant formula,
baby food and even water, depending on the age of the child. Babies feed differently with artificial teats than from a breast. When feeding from the breast, the tongue massages the milk out rather than sucking, and the nipple doesn't go as far into the mouth; when feeding from a bottle, 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 induce the infant to prefer 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.
Tandem breastfeeding
Feeding two children at the same time is called
tandem breastfeeding The most common reason for tandem breastfeeding is the birth of
twins, 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.
In cases of
triplets or more, it's 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's 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.
Shared breastfeeding
It used to be common worldwide, and still is in
developing nations such as those in
Africa, for more than one woman to breastfeed a child. Shared breastfeeding is a risk factor for
HIV infection in infants. A woman who is engaged to breastfeed another's baby is known as a
wet nurse.
Islam has
codified the relationship between this woman and the infants she nurses, and also between the infants when they grow up, so that milk siblings are considered as blood siblings and
cannot marry. Shared breastfeeding can incur strong negative reactions in the
Anglosphere; American feminist activist
Jennifer Baumgardner has written about her experiences in
New York with this issue.
Weaning
Weaning is the process of introducing the infant to other food and reducing the supply of breast milk. The infant is fully weaned once it relies on other food for all its nutrition and it no longer receives any breast milk. Most mammals stop producing the
enzyme lactase at the end of weaning, and become
lactose intolerant. Many humans have a mutation that allows the production of lactase throughout life and can drink milk - usually cow or goat milk - well beyond the age of weaning.
In the past,
bromocriptine was sometimes used to reduce the
engorgement experienced by many women during weaning. However, it was discovered that when used for this purpose, this medication posed serious health risks to women, such as
stroke, and the U.S.
FDA withdrew this indication for the drug in 1994.
History of breastfeeding
infant formulas appeared on the market in the mid 19th Century but their use didn't become widespread until after
WWII. As the superior qualities of breast milk became better-established in medical literature, breastfeeding rates have increased and countries have enacted measures to protect the rights of infants and mothers to breastfeed.
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 correlate breastfeed, 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. This may be evidence that breastfeeding acceptability is based on cultural acceptance, and that acceptance is related to socioeconomic status in the mother’s culture. 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.”
Economic factors of breastfeeding
Women who are less likely to breastfeed are more likely to incur medical bills due to the lack of protection that breast milk gives to the child. In the case of poor mothers this combined with the extra cost of artificial feeding could result in more debt, and even worse poverty. The birth of a child puts an economic strain on parents, but this is exacerbated if the baby isn't breastfed. This is also linked to Michael Marmot’s theory of status syndrome, in which status level, determined by education, wealth, occupation, and social prestige, determines how healthy people are.
Many programs have been created to help reduce the disparity between low income and African American mothers and other mothers in choosing to breastfeed. These programs include the WIC, WHO, the World Health Organization, UNICEF, United Nation’s Children’s Fund, and La Leche League International. They work to educate women about breastfeeding and try to alleviate some of the stresses in breastfeeding in today’s society. However, according to the latest figures, WIC’s efforts have not been successful in increasing the number of breastfed infants. If these organizations had a little more success, the disparity between the socioeconomic groups could be reduced, and result in a healthier general population. Higher breastfeeding rates won't reduce the socioeconomic disparity, but it might help to increase the health of those who are poor and disadvantaged. So, breastfeeding could help to alleviate the economic stresses and poor health of the working class and the poor.
