<unk>  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<unk>  for the first six months, without the supplement of infant formula milk or solid food.
According to a 2001 WHO report, alternatives to<unk>  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 situations where the mother is taking certain drugs or is infected with tuberculosis or HIV).  Experts disagree about how long to breastfeed to gain the greatest benefit, and about 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<unk>  and exclusive<unk>  for the first six months of life. AAP recommends at least one year of<unk>  and exclusive<unk>  for the first six months of life. Exclusive<unk>  for the first six months of life "provides continuing protection against diarrhea and respiratory tract infection" that is more common in babies fed formula. The World Health Organization (WHO) and American Academy of Pediatrics (AAP) both stress the value of<unk>  for mothers and children.  While recognizing the superiority of<unk> , regulating authorities work to make artificial feeding safer when it is not used.
