Think you know your baby? Think again. This beautifully shot, heart-warming and scientifically revealing film, narrated by Martin Clunes, brings you babies as you've never seen them before. The first two years of our lives are the most critical of all. We grow more, learn more, move more and even fight more than at any other time in our life. We have to master the complex skills of walking, talking and relating to the world around us. But we are not yet built like an adult. We have more bones in our body at birth than an adult does, yet we don't have kneecaps. We laugh 300 times a day as a baby, but in the first few months we can't produce tears when we're upset. Secret Life of Babies reveals all these facts and more, telling incredible stories of babies' resilience and survival skills to boot. This film will surprise, move, amaze and delight all those who have ever come into contact with a baby, whilst taking you from the moment of birth, through to the point where language begins, memories start to kick in, and a new phase of their lives takes over. This is the Secret Life of Babies.
