Books with title Mummy Never Told Me

What are tummy buttons for, and how do they get there? What does the tooth fairy really look like? Why do grown-ups have hair in their ears and up their noses, but sometimes none on their heads? Why do Mummy and Daddy lock you out of their bedroom, and where do they go at night? Babette Cole explores these questions and many more with her wonderfully sharp text and riotously funny illustrations.
