In the first year, one of a baby's developmental milestones is mastering the imitation of others and learning to play simple games. The hands-down favorite at this age is Peekaboo, and this flap book offers babies an interactive game of Peekaboo. Each spread features a close-up of a Sesame Street Muppet hiding behind sturdy, hand-shaped flaps that open to reveal the character's full face. Simple rhyming text offers clues to help a very young child identify the character before opening the flaps.Lewison, Wendy Cheyette is the author of 'Peekaboo! I See You!' with ISBN 9780375815126 and ISBN 0375815120.
