Abstract

Background: Preterm infants have shorter breastfeeding duration than that of term infants. Details of postdischarge feeding methods and difficulties are needed to inform the care of preterm breastfeeding dyads.

Purpose: To describe postdischarge breastfeeding characteristics of mother-preterm infant dyads up to 12 weeks corrected gestational age (CGA).

Methods: A prospective observational study of preterm dyads (birth 24-33 weeks' gestation) that fed their mother's own milk (MOM) at discharge from a neonatal unit in Perth, Western Australia. Feeding method and frequency, breastfeeding duration, difficulties, and nipple shield use were recorded at 2, 6, and 12 weeks CGA.

Results: Data were obtained for 49 mothers (singleton infant n = 39, twins n = 10). At 12 weeks CGA, 59% fed any MOM with 47% exclusively fed MOM and 31% fully breastfed. Nipple shield use reduced from 42% at 2 weeks CGA to 11% at 12 weeks CGA. Compared with mothers who exclusively fed MOM at discharge (n = 41) those who fed both MOM and infant formula (n = 8) were more likely to wean before 12 weeks CGA ( P < .001). Weaning occurred before 2 weeks CGA in 12/19 (63%), with low milk supply the most frequently cited reason.

Implications for practice: Most mothers with a full milk supply at discharge successfully transition to predominant breastfeeding. Frequent milk removal needs to be prioritized throughout the preterm infant's hospital stay.

Implications for research: Examination of facilitators and barriers to early and continued frequent milk removal across the postpartum period is required to identify strategies to optimize lactation after preterm birth.
