There is no evidence that breastfeeding a child beyond infancy is harmful. Quite the opposite is true: breastfeeding benefits toddlers and young children, both nutritionally and psychologically. Breastmilk remains a valuable source of protein, fat, calcium, and vitamins well beyond two years of age. (1) Immunities in breastmilk become more concentrated as nurslings mature; (2) at the same time, the likelihood of allergies decreases. (3) Mothers who nurse past infancy derive benefits as well, including a decreased risk of breast and ovarian cancer the longer she continues nursing. (4)
Breastfeeding is a warm and loving way to meet the needs of toddlers and young children. It not only perks them up and energizes them; it also soothes the frustrations, bumps and bruises, and daily stresses of early childhood. In addition, nursing past infancy helps little ones make a gradual transition to childhood. In fact, prolonged nursing is associated with better social adjustment. (5)
