I got these books for my son, because of the great reviews. All the reviews failed to mention that most of the content on the book talks about "poop", butts, and gross stuff. I mean, maybe this is the reason why kids find these books so entertaining?. The books have vibrant colors, and yes my son loves to read them, but I don't really love when he reads it a loud to me and there is a poop comment every time. I have to admit he loves to check the last pages and try to draw the characters.
