The definitive new science- and data-led guide to baby sleep for new parents, from pioneering infant sleep researcher Professor Helen Ball.

How babies sleep is both exceedingly simple and excruciatingly complex. It is simple because it is based on a few straightforward biological principles that affect babies all over the world. It is complex because we have made it so.

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, pioneering infant sleep researcher professor 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 and experiment with strategies that work for you and your family.
