Breastfeeding has health advantages for both children and their mothers. Evidence shows that babies who are breastfed have fewer infections and allergic skin rashes than formula-fed babies and are also less likely to have sudden infant death syndrome (SIDS). After breastfeeding ends, children who were breastfed are less likely to develop asthma, diabetes, obesity, and childhood leukemia. Women who breastfeed have a lower risk for type 2 diabetes, breast cancer, and ovarian cancer than women who have never breastfed. For these reasons, the American Academy of Pediatrics, the American Academy of Family Physicians, and the American College of Obstetricians and Gynecologists recommend breastfeeding as the preferred choice for feeding babies. However, a 2002 survey showed that only 71% of American children had ever been breastfed, only 35% were breastfed at 6 months of age, and only 16% were breastfed at 12 months of age.
