The perfect picture book for any anxious young child waiting for their new brother or sister to arrive. When Liam and Mary's mum and dad bring their new baby brother home from the hospital they also bring some presents: for Mary, some building blocks and for Liam, a family of hippos. But the baby hippo of the family keeps going missing. First he gets eaten by a crocodile, then trampled by an elephant until finally the littlest hippo gets stuck after taking a swim in the toilet. This is a warm, sensitive and reassuring book about the arrival of a new baby in the family, written by an expert in the field of child development.
