Breast-feeding is feeding a baby breast milk directly from the breast or from a bottle after expressing the milk with a pump. Breast milk provides the best nutrition for a baby.

All major professional medical organizations that focus on children, such as the American Academy of Pediatrics (AAP), recommend breast-feeding for at least the first year of a baby's life. This recommendation includes feeding a baby only breast milk for the first 6 months. Other foods, such as cereal, are then gradually introduced while continuing to breast-feed.
