One of the sweetest animal Christmas stories I’ve ever seen:
Who Is Coming to Our House? by Joseph Slate, illustrated by Ashley Wolff
It’s very short and simple. All the animals in the stable know that someone is coming to their house, and they wonder and wonder who it could be. They do what they can to prepare for their guest, and at the end, everyone welcomes Him.
A very warm, gentle, and happy book (and Mary is shown lying down and snuggling the baby after giving birth, which I always appreciate!).
I’ve linked to the sturdy board book version, because I think little guys will appreciate the warm colors and friendly animal faces — but I always find the little story moving and comforting, myself.
