A string of comically stylized parent-and-child animal pairs say "good night" and "sleep tight" to each other in masterful couplets—a chick's "cheep cheep" is answered by a chicken's "cluck cluck"; a puppy's "ruff ruff" is returned with a dog's "woof woof"—all leading up to a human toddler and her dad at bedtime! The second title in a brand-new board book series on animal (and human) first words by award-winning author/illustrator Ethan Long is sure to make tucking in a lot more fun!
