Everyone Poops by Taro Gomi
"Everyone Poops by Taro Gomi is part biology textbook, part sociological treatise and all celebration of a very natural process. Both my daughters begged me to read the book over and over again. They marveled at the enormity of the elephant`s poop and searched with the skill of a scientist for the tiny specks which represent bug poop. The text is simple and straightforward but not without humor.
