Breastfeeding
Suckling and nursing are synonyms. For other uses, see Nursing (disambiguation) and Suckling (disambiguation) Breastfeeding is the feeding of an infant or young child with breast milk directly from female human breasts (i.e., via lactation) rather than from a baby bottle or other container. Babies have a sucking reflex that enables them to suck and swallow milk. It is recommended that mothers breastfeed for six months or more, without the addition of infant formula or solid food. After the addition of solid food, mothers are advised to continue breast-feeding up to a year, and can continue for two years or more. Human breast milk is the healthiest form of milk for babies.[1] There are few exceptions, such as when the mother is taking certain drugs or is infected with human T-lymphotropic virus, HIV, or has active untreated tuberculosis. Breastfeeding promotes health and helps to prevent disease.[2][3][4] Artificial feeding is associated with more deaths from diarrhea in infants in both developing and developed countries.[5] Experts agree that breastfeeding is beneficial, and have concerns about artificial formulas but there are conflicting views about how long exclusive breastfeeding remains beneficial.[6][7][8] The World Health Organization (WHO) and the American Academy of Pediatrics (AAP) emphasize the value of breastfeeding for mothers as well as children. Both recommend exclusive breastfeeding for the first six months of life and then supplemented breastfeeding for at least one year and up to two years or more.[9][10] While recognizing the superiority of breastfeeding, regulating authorities also work to minimize the risks of artificial feeding.[7] Breast milk

Not all the properties of breast milk are understood, but its nutrient content is relatively stable. Breast milk is made from nutrients in the mother's bloodstream and bodily stores. Breast milk has just the right amount of fat, sugar, water, and protein that is needed for a baby's growth and development.[11] Because breastfeeding uses an average of 500 calories a day it helps the mother lose weight after giving birth.[12] 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. The quality of a mother's breast milk may be compromised by smoking, alcoholic beverages, caffeinated drinks, marijuana, methamphetamine, heroin, and methadone.[13] Benefits for the infant

Scientific research, such as the studies summarized in a 2007 review for the U.S. Agency for Healthcare Research and Quality (AHRQ)[14] and a 2007 review for the WHO,[15] has found many benefits to breastfeeding for the infant. These include: Greater immune health

During breastfeeding, antibodies pass to the baby.[16] This is one of the most important features of colostrum, the breast milk created for newborns. Breast milk contains several anti-infective factors such as bile salt stimulated lipase (protecting against amoebic infections), lactoferrin (which binds to iron and inhibits the growth of intestinal bacteria)[17][18] and immunoglobulin A protecting against microorganisms.[19]

Fewer infections
Among the studies showing that breastfed infants have a lower risk of infection than non-breastfed infants are: * In a 1993 University of Texas Medical Branch study, a longer period of breastfeeding was associated with a shorter duration of some middle ear infections (otitis media with effusion) in the first two years of life.[20] * A 1995 study of 87 infants found that breastfed babies had half the incidence of diarrheal illness, 19% fewer cases of any otitis media infection, and 80% fewer prolonged cases of otitis media than formula fed babies in the first twelve months of life.[21] * Breastfeeding appeared to reduce symptoms of upper respiratory tract infections in premature infants up to seven months after release from hospital in a 2002 study of 39 infants.[22] * A 2004 case-control study found...
