This book is excellent! At first I thought it was a little gross, but both of my boys understood the concept and love reading it over and over. I really do think it helped with their potty training. I would highly recommend it.
This book is not what I thought it would be based on the title. It could be viewed as a cute little children's book about poop / pooping but there is nothing that I would call science in it. The book is basically just pictures of different animals and saying each one of them poops.... might be a fun book for a 5-ish year old who's in that "everything-bodily-is-funny" stage.
Great for use when potty-training. Not all children have fish, rabbits, goats, a cat, a dog, nor have been to the zoo to see the larger animals be cleaned up after. Science & health, and the body's normal habits and needs as far as end products of the gastrointestinal tract. Health.
There is one page, page 23, where some child has dark-pencil colored what I suggest is a great area to have colored over.
