Relationship Between the Rates of Breast Milk Production of Preterm Mothers in the First Week Post-Delivery and Continuation of Breastfeeding Through Discharge

Abstract

BackgroundMothers of preterm infants born between 26- and 35-weeks’ gestation often report challenges with maintaining a pumping schedule and experience perceptions of low milk supply, both of which may contribute to early termination of breastfeeding within the first few weeks.PurposeThe purpose of this study was to assess the relationship between the amount of expressed milk volumes in the first 2 weeks after delivery and infant’s continuing to receive mother’s milk at hospital discharge. These results were part of a larger study that examined multiple maternal variables that may impact the amount of milk volumes and continuation of breastfeeding in the preterm infant admitted to the NICU.MethodsMothers of infants (N = 37) in the NICU were recruited for this correlational, longitudinal study. Data was collected at 24–48 hours post-delivery, at 2 weeks, at 4 weeks from mothers participating in the study and from infant chart reviews.Results/OutcomesMothers who reported higher expressed milk volumes at 3 days post-delivery had consistently higher volumes of expressed breast milk and a higher percentage of continued breastfeeding at hospital discharge. There was no statistically significant relationship between breastfeeding self-efficacy scores, socio-demographic variables, or pumping frequency and the percentage of infants receiving breast milk at hospital discharge. Overall, 76.4% of the infants enrolled in the study were receiving 100% of their intake with fortified mother’s milk at hospital discharge.Discussion/Implications for PracticeThe use of a breast pump log in the first 2 weeks to monitor milk volumes may assist in predicting mothers who are at risk of lower milk supply and early discontinuation of breastfeeding.
