My mom got the coolest book to read to the boys (and future grandchildren)! It's a book about a dog named Jingle and it comes with a little stuffed animal that actually interacts with you as you read. Like, when you read, "that made Jingle sad," the little dog whimpers. And when you read, "good boy, Jingle," he barks and pants. And it's not just two noises, but tons. It really is incredible. I think she got it at Hallmark if you're interested.
And here is Mimi reading Jingle to the boys.
