CME EDUCATIONAL OBJECTIVES: 1.Review the advantages and disadvantages of donor-banked milk over informal milk sharing.2.List disadvantages of proprietary infant formula for use as supplementation.3.Determine the primary ethical concerns when electing to use donor human milk versus propriety infant formula for supplementation. The benefits of breast-feeding, as well as the risks of some artificial formula, are well known. This growing recognition of the advantages of breast-feeding is reflected in the increased incidence of breast-feeding in recent years. However, one of the most common reasons for premature weaning is low milk supply, perceived or real, followed by nipple or breast pain. Given the increased awareness of the superiority of breast milk, however, more parents are turning to human donor milk to supplement their babies after they have been weaned.
