Mothers should be told the benefits of breastfeeding, including infant immunity, emotional satisfaction, mother-infant bonding, and economic savings. The period of amenorrhea associated with frequent and consistent breastfeeding provides some (although not reliable) birth control until menstruation begins at 6–12 months postpartum or the intensity of breastfeeding diminishes. Even a brief period of nursing is beneficial. Transfer of immunoglobulins, macrophages, and lymphocytes in colostrum and breast milk immunoprotects the infant against many systemic and enteric infections. The intestinal flora of breastfed infants inhibit the growth of pathogens. Breastfed infants have fewer bacterial and viral infections, fewer GI tract infections, and fewer allergy problems than bottle-fed infants. Furthermore, they are less apt to be obese as children and adults.
