Have you ever been around 4 year olds? They are obsessed with anything potty, booty or underwear related. They go into hysterics if someone farts or burps.This book is for them.Is the story silly - oh yes. A bear finds a backpack full of underwear and tries them all on until he finds the right ones that fit. That's it.And the kids think it is the funniest damn book they have ever read. The kids read it to each other and bust out laughing. They read lots of books, some more silly than others. I don't take the silly books away - it's part of them learning that books are fun. But that's the way we roll. Your mileage may vary.
