Babies love playing peekaboo from about six months onward -- and once they latch on to this simple game, they can't get enough of it! DK's Peekaboo books make the most of this fun interactive activity with flaps that open to reveal appealing babies and toys. The Baby Loves Peekaboo board book shows how Teddy, Dolly, Big Monster, Kitty, and Baby all love playing peekaboo.
