In this story, a little owl is the only creature that is still awake in the night, and he flies around to observe the different styles in which other animals sleep.

A Book of Sleep is one of those classic bedtime books for babies and young toddlers that parents won’t mind re-reading because the writing is simple and soothing, and the artwork is great — lots of interesting details with a dash of whimsy on every frame-worthy page, all painted in sleep- and night-appropriate muted colours.
