Babies: Wonderful World

The final episode investigates the latest research into how we become independent. We will look at the huge transition babies make as they learn to crawl. New research suggests that crawling triggers a new understanding about the world and its hazards. Professor Elisabeth Hill tests newly crawling babies with a visual cliff - an optical illusion made of perspex that looks like a sheer, vertical drop - to see how they react.
