This title is a Channel 4 TV tie-in, which examines the development of children between the ages of two and 12. Focusing on behaviour and the mind, it charts the achievements that mark the journey to becoming a fully-fledged person. Illustrated with full-colour photographs, the book examines how children gain a sense of self; navigate the social world; learn the vital skill of lying; make sense of the physical world; come to understand life, death and sex; and reach full independence.
