This box set includes the most popular Karen Katz illustrated lift-the-flap board books: Where Is Baby's Belly Button?, Where Is Baby's Mommy? and Toes, Ears, & Nose. Young children love peeking under the flaps to find their belly button, or looking for their toes, and playing hide-and-seek with mama. This trio of baby's best board books provides hours of lift-the-flap fun in one box!
