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.
When mummies and daddies go to work, young children often wonder what they are doing - are they in an office, do they drive a truck, are they helping people? Some children also worry about who will look after them when their parents are away and if their mum and dad will come back home again. These stories may help to calm their fears.
