I was under the impression that this book would give advice on how to encourage a child to poo on the toilet, not be a very short comic strip on the subject. It's ok as something to show children, but not at all what I thought I was buying.
This book has not helped with my child's withholding issues though I imagine it would help most. Regardless, it's a fun read and my child now knows the words off by heart and says the words with me. I would recommend it.
