Preterm infants have barriers to successful breastfeeding that include oral feeding immaturity and high nutritional needs. Therefore, successful preterm infant breastfeeding requires increased counseling and equipment support compared to full-term infant breastfeeding. Inpatient preterm infant care has responded to these barriers, with specialized preterm infant lactation support. Unfortunately, for preterm infants, the onset of feeding maturity often coincides with hospital discharge and, therefore, inpatient, specialized lactation support ends just as the infant initiates nutritive feeding at the breast. Therefore, the success of preterm infant breastfeeding relies on the home environment and the community pediatric caregivers. A program has been created to provide this specialized preterm infant/mother outpatient lactation support. The program includes in-home availability of a hospital-grade electric pump and an infant weigh scale and pediatric clinic-based lactation counseling support. Fourteen pediatric practices are included in this study. Seven practices were randomized to intervention and seven were randomized to be controls.
