The Shelf Challenge is back! That's a very good thing indeed! Especially when you get to start with a book like Tuck Me In! by Dean Hacohen and Sherry Scharschmidt. I discovered this book in our collection shortly after our now 2 1/2 year-old was born and I like the book even more now that he can read it with me. The premise is simple: a bunch of wild animals are going to bed and each need to be tucked in. Solution? Have the reader tuck in each character by flipping a half-page blanket.
