Joining a nursery, playgroup or other pre-school setting is often a young child's first big 'solo' adventure, just like that first time they're alone with a babysitter - no matter if it's Grampa, Auntie or someone new. Most children will look forward to the experience, but some will find it worrying. Sharing a book about other children's experiences can help to make things less worrying and get them excited about making new friends and having new adventures.
