What is funnier or more interesting to kids than poop? They constantly talk about and question it from a very young age, perhaps spurred on by parents always asking kids about their own need to do it! In this book, readers explore why we poop and how we do it. They'll learn yucky facts they want to know, such as why poop smells, as well as explore how poop can tell us about our health. A diagram aids comprehension of the science information.
