It is optimal for preterm infants to receive their mother fs own milk, but mother's milk output is often too small to meet infant needs. We reviewed medical records for mothers delivering at <32 wk (Jan/2008–Dec/2010) to determine if early or frequent pumping increases mother fs milk output. Early Group (EG, n=20) mothers initiated pumping <12 h, while the Late Group (LG, n=20) initiated pumping >;12 h, after delivery. LG mothers were randomly selected to frequency match EG mothers on gestational age; EG and LG mothers did not differ on birth weight, maternal age, delivery mode or parity. EG were more likely than LG mothers to have above median (p=0.004) milk output on postpartum day 1, but not for days1–5. However, frequency of pumping predicted above median milk output over days 1–5 (p=0.035). Further, more frequent pumping on day 3 was associated with more exclusive breastfeeding at discharge (p=0.047). Thus, in this sample of Japanese mothers who delivered preterm, we did not observe differences in milk output after day 1 in those who initiated pumping within 12 h of delivery, but pumping frequency was associated with milk output over days 1–5 and exclusive breastfeeding at discharge. A larger study of early and frequent pumping is ongoing.
