Helen Ball is Professor of Anthropology and Director of the Infancy and Sleep Centre at Durham University.  Helen reveals how choosing a biological anthropology class during her human biology degree led to her becoming an anthropologist, and why she switched from studying primates in Puerto Rico to infant and parent sleep.  She chats about her research on bed sharing; the development of the Baby Sleep Info Source; and career highlights – her involvement in changing the SIDS messaging around bed-sharing and the impact of parent-infant proximity on breastfeeding.
