Young children ask lots of questions. It's one of the ways they learn about themselves and about their bodies.

Join siblings Nellie and Gus on a day out at the beach as they ask questions and figure out the similarities and differences between boys and girls in a humorous and honest way. With charming, informative words and pictures, this book will reassure children that whether they have a girl’s body or a boy’s body, their bodies are truly amazing – and totally wonderful! A new picture book series for young children from best-selling author Robie H. Harris, illustrated by Nadine Bernard Westcott.
