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 behavior is both mystifying and fascinating. Using the latest specialist filming techniques, this program reveals the 'natural history' of a baby starting with newborns and following their growth and development as they become toddlers. Get ready to see your baby in a whole new way.
