 However, in healthy mothers, there are many benefits for infants who are breastfed.The World Health Organization recommends that mothers breastfeed their children for the first two years of life, whereas the American Academy of Pediatrics and the American Academy of Family Physicians recommend that mothers do so for at least the first six months, and continue as long as is mutually desired.Infants who are breastfed by healthy mothers (not infected with HIV/AIDS) are less prone to infections such as "Haemophilus influenza, Streptococcus pneunoniae, Vibrio cholerae, Escherichia coli, Giardia lamblia", group B streptococci, "Staphylococcus epidermidis", rotavirus, respiratory syncytial virus and herpes simplex virus-1, as well as gastrointestinal and lower respiratory tract infections and otitis media.
