Sam has a great many worries. He thinks there may be a volcano under the house, cobras in the garage, he may lose his library books, and he doesn't like the idea of vampires and monsters at all. He is also feeling guilty because he steals biscuits from the tin. When he can't sleep, mum comes along and is sensibly reassuring (except about the biscuits because he hasn't told her about those). Sam and his Teddy are still worried though, because 'Mother's don't know everything'. They make a pact: Teddy will do all the worrying at night while Sam sleeps, and Sam can take on the daytime worrying while Teddy sleeps. It works a treat. The fact that Sam doesn't worry during the day doesn't bother Teddy's sleep at all. Imaginative and beautifully illustrated. A unique answer to a common problem.
