Don’t Go There! by Jeanne Willis and Hrefna Bragadottir

Lid up, pants down, bottom on the seat! They mustn't have toilets in outer space, because this baby Martian keeps going in the wrong place: a bird bath, a bin, an up-turned hat...

Perhaps if he masters The Toilet Song, he might learn where to go.

This is an excellent story book for teaching your child potty or toilet training.
