What can a baby see and hear? How does a baby explore the world? Why can they swim underwater? How do they communicate? And why do toddlers have temper tantrums? The first three years are the most important of a human’s entire life - it’s when we learn to walk, talk and socialize. But as an adult, baby behaviour is both mystifying and fascinating. Featuring babies of all shapes and sizes, Secret Life of Babies discovers how a baby’s rapidly changing body affects its behaviour and also meets the miracle babies who have survived against all the odds.
