From a pioneering infant sleep researcher, this book is a salvation for parents of newborns trying to maintain a nighttime routine. Over the past century and a half, we have tried to manipulate baby sleep to fit with the rapidly changing nature of adult lives. The mismatch we have created with our babies’ biology is framed as ‘baby sleep problems’, and infants are often ‘treated’ using behavioural and clinical interventions. But it is not baby sleep that needs fixing—only our understanding of it.    In How Babies Sleep , Helen Ball brings together cutting-edge science, anthropological insight, and practical advice to provide parents with everything they need to help them confidently—and sanely—navigate the first 365 night-times with a new baby. It will teach you how to harmonise your needs with those of your infant, and empower you to reject approaches that make you uncomfortable. Feel confident in a strategy that works for you and your family!
