MY baby

We recently borrowed a book from the library about two dogs. Two dogs who's people have a new baby- and they are not happy about it. They want to bite it, they want to bury it, they pee on the rug, they don't get the attention they used to. Then grandpa comes to visit. And even though they hate the baby, it's theirs, and they don't think grandpa should come near it. "It's OUR baby to hate as much as we want to, and maybe even to like, just a little bit".
