Dr Kathryn Hesketh (pictured) is a Behavioural Epidemiologist and Principal Research Fellow at University College London. She is an expert in movement behaviours during the transition to parenthood and during the first five years of life, seeking to understand how we can better promote physical activity and play during pregnancy, postnatally, and in the preschool period.

Professor Helen Dodd is Professor of Child Psychology at the University of Exeter Medical School. She is an expert in children’s play and mental health, with a particular interest in child anxiety.

Dr Hesketh and Professor Dodd have recently published the results of the British Preschool Children’s Play Survey, which aimed to assess when, where and how adventurously young children in the UK are playing.
