A dog with a heart-shaped patch over one eye peeks from behind a squishy fabric heart on the cover of this lift-the-flap board book. “Who’s that hiding under there?” Lift the chair-shaped flap on the facing page to reveal, “Peek-a-boo! / a brown bear in a chair.” Flaps lift to reveal in turn a dog, cat, cow and a mirror. Peek-a-boos are right up the developmental alley for the board-book audience, but these flaps are made of a regrettably flimsy stock, which clumsy toddler fingers will have difficulty lifting. For as long as they’re willing to let their grown-ups drive, this will please them well enough. The publisher gives a 3-6 age range; while preschoolers’ small-motor skills can handle the flaps, there’s not enough substance to sustain their interest. (6 mos.-2)
