Your Own Big Bed by Rita M. Bergstein, illustrated by Susan Kathleen Hartung (Viking, 2008)
In this sweet picture book, a small boy learns about different animals and how they grow - right along with the story of his own birth and growth. As he gets bigger, he is ready to trade his crib for his very own big bed. This is a very gentle and comforting look at getting bigger and transitioning into a new bed. Recommended for anyone with a child getting ready to make that big childhood transition from crib to bed.
