The American Academy of Pediatrics recommends nursing for 12 months, exclusively for the first six. “But a mom should stop breastfeeding if she realizes that she’s no longer enjoying it, even though it has myriad benefits,” says Erica Brody, M.D., director of pediatric breastfeeding medicine at the Icahn School of Medicine at Mount Sinai, in New York City. On the other hand, there’s no need to wean as soon as your child turns 1, if prolonged breastfeeding makes you both happy.
