An atmospheric exploration of childhood worries and how to overcome them, by the 2000 Hans Christian Andersen Medal Winner. Billy is a bit of a worrier. He worries about hats and shoes. He worries about clouds and rain and giant birds. Most of all he worries about staying at other people's houses.
His mum and dad try to help, but still Billy worries ... until a visit to his grandma's shows him how to overcome his fears with the aid of his imagination - and some tiny worry dolls.
