It is estimated that with adequate motivation and support, most mothers can establish and sustain prolonged breastfeeding. Even with motivation and support from their families, employer, community, and the medical system, mothers with certain medical and psychosocial conditions may not meet their breastfeeding goals. In rare situations, breastfeeding is not recommended because of maternal or newborn/infant indications. To provide appropriate guidance around breastfeeding, health care practitioners should review prior breastfeeding history, breast health and surgical history, and general medical history and examine the breasts as indicated.
