Boo can roar, kick and bite. But so can Geraldine. And she's not going to be left out! She roars very loudly, kicks Mummy and bites Daddy. Things are looking bad and only Geraldine's toys seem to understand her. But when Geraldine cries, Baby Boo cries too and suddenly everything changes. "Don't cry, Baby Boo," says Geraldine. "Don't cry." Now there is Mummy and Daddy and Geraldine and Boo, a happy family who all love each other.

This witty and sensitive picture book perfectly captures the feelings of a child with a new baby in the family.
