Abstract

Milk production was examined in 39 lactating mothers of non-nursing preterm infants from 2 tertiary care centers. The purposes of this study were (1) to compare milk production of those using sequential single (SEQ) or simultaneous double (SIM) breast-pumping regimen, and (2) to examine the relationship of selected variables to inadequate (<3500 g/week) and adequate (≥3500 g/week) milk production. In multivariate analysis, mothers using SIM produced a similar amount of milk by weight during weeks 2 to 5 postpartum compared to those using SEQ. A logistic regression model including frequency of kangaroo care, frequency of pumping, high versus low income, and previous breastfeeding experience was predictive of mothers producing adequate versus inadequate milk volume 79% of the time. All of the mothers producing >3500 g at week 2 produced adequate amounts of milk at weeks 4 and 5. None of the mothers producing <1700 g at week 2 reached adequate production by weeks 4 and 5. Of the remaining mothers who produced 1700 g to 3500 g at week 2, 54% achieved adequate production during weeks 4 and 5 postpartum.
