This cute lift-the-flap board book takes a favorite babyhood activity to a whole new level. On each two-page spread appears the question “Peekaboo! Who’s there?” and an animal covering his eyes. When the reader lifts the flap, there is the same critter in action: a leaping sheep and chewing cow, for example. Cocoretto’s bright illustrations of smiling creatures in their natural habitats add to the charm of this kid-friendly introduction to the animal kingdom. (Note: I just shared the books in this series with my three-year-old grandson, a budding literary critic, and he delighted in identifying the animals.)
