I know that this is a kids book. And we've loved other books by the same author. I know he was trying to show the frustration of the older brother with the younger brother. But, phrases like "poopy head" and such do not seem appropriate to this age who are still learning to filter what is appropriate. I gave these three books to my oldest daughter (an avid reader) for her birthday. She was more than thrilled to "share" with us the words she found in them. I know she has been somewhat sheltered, but honestly, do we really need to steep our children in the progressive decline in civil language. She is not allowed to speak nastily to her little sister or anyone else for that matter. To say the least, I am disappointed.
