Many breastfed infants receive expressed breast milk as well as feeding from the breast. We explored the prevalence and outcomes of breast milk expression, and whether feeding other than directly from the breast prior to hospital discharge decreased the proportion of infants receiving any breast milk at sixmonths. Postpartumwomen who had a healthy singleton term infant, intended to breastfeed and spoke English were recruited from three hospitals in Melbourne, Australia – two public and one private. Data were collected at recruitment and by telephone interview at three and six months postpartum. Descriptive statistics were used. In total, 1003 women were recruited between 24 and 48h after birth between July 2009 and April 201; 50% were primiparous, of whom 45% already had a breast pump. At recruitment, 48% of infants had been fully breastfeeding at the breast, 47% had received at least some expressed breast milk and 23% had received some formula. Only 36% of primiparas had been fully feeding at the breast. At six months, infants who had fed only at the breast by the time of recruitment were more likely to be continuing to have any breast milk than thosewhohad received any expressedbreastmilk and/or infant formula (76% vs. 59%; OR 1.8, 95% CI 1.27, 2.46; adjusted for parity, type of birth, breastfeeding intention, perceived breastfeeding problems at recruitment and education). Less than half of the infants had fed only at the breast in the first days of life. Expressing breastmilk andbreast pumpuse are commonpractices formothers of healthy term infants. The use of expressed breastmilk in hospital was associated with decreased breast milk feeding at six months. Where possible, clinicians should encouragemothers with healthy term infants to only feed directly from the breast.
