The Hat by Jan Brett
A little girl loses a mitten to a hedgehog who gets his nose stuck in it so that it looks like he is wearing a hat. The mother hen sees him and laughingly asks him what is on his head. He tells her it’s his beautiful new hat. The gander, the barn cat, the dog, the pig and the horse all laugh at the hedgehog, too, but secretly wish they all had something cool to wear. By the end they all look like a winter fashion show gone terribly wrong. Your kids will love the illustrations, especially the ones on the side of each page that give them a little hint as to what is coming up next in the story. I think this is the first Jan Brett book I ever read and it is probably one of her most famous.
