Flaherman VJ, et al. - Through a randomized clinical trial 164 exclusively breastfeeding mothers and dyads of mothers who were not yet producing copious milk, the researchers intended to determine for at-risk neonates, whether structured, short-term formula supplementation affects the proportion still breastfeeding at 6 and 12 months. Early limited formula (ELF, 10 mL formula fed after each breastfeeding until mothers produced copious milk) was included in the intervention. However, any improvement in breastfeeding duration was not related to ELF.
