Bedtime in the Forest by Kazuo Iwamura

Every child who has ever begged to stay up late will relate to this humorous bedtime story. Mick, Mack, and Molly are three adorable squirrel siblings who decide they aren't ready for bed. Since the owl children are wide awake and playing, they figure they should be too. Kids will relish every minute of this late-night escapade as these squirrels head out for some midnight fun instead of going to sleep.
