Methods: We conducted a descriptive cohort study at a tertiary-care pediatric hospital. Subjects included infants <20 days of age with major congenital malformations. According to the feeding pattern, the following three groups were identified: exclusively breastfed (EB); alternating breast and formula (ABF), and exclusively formula (EF). Follow-up interviews were conducted on a monthly basis until the infants were 6 months of age. The feeding pattern was determined during each visit. Reasons for changing the breastfeeding pattern were explored. ©Archives of Medical ResearchenResource Types::text::journal::journal article
