From award-winning author Jennifer Ward and Caldecott Honor illustrator Robin Page, this nonfiction picture book interweaves informative poems and prose to show the many different ways animals snooze!Just like people, all animals need sleep, but not all animals sleep in the same way. When dolphins sleep, half their brain stays awake. Snakes sleep with their eyes open. Giraffes sleep in five-minute intervals, while koalas sleep for twenty-two hours a day! From grizzly bears to hummingbirds, there are creatures of all sizes and habitats to wish a good night in this cozy and compelling book.
