Birth & up. Have fun playing a game of peek-a-boo, going to the beach, and learning how to get ready for bed with baby in this vibrantly-illustrated Indestructibles® Baby Book set. Your little one will enjoy stories they can literally "chew on." This set of 3 paperback books are illustrated by Kate Merritt and contain 6 pages each. Soft and paper-like, these books are chew proof, rip proof, non-toxic, and dishwasher and washing machine safe!
