The Feasibility of Drug Delivery to Infants During Breastfeeding

This study aims to give a vitamin B12 supplement to babies during breastfeeding. 30 mother-infant pairs will be recruited. The supplement will be placed into a nipple shield, both of which are commercially available, and the mother will breastfeed her baby as usual. Before and after the feed, we will 1) collect a small blood sample from the baby to see whether the vitamin levels in the infant have increased, 2) ask the mother to participate in two short interviews about her expectations and experiences using the Therapeutic Nipple Shield.
