Indestructibles Indestructibles are the books built for the way babies read. They are 100 percent baby-proof, chew-proof, rip-proof, and drool-proof. Printed on a unique nontoxic, paperlike material that holds up to anything babies can throw at it - gumming, spilling, dragging across the floor - Indestructibles are the little books that could. They"re indestructible. And if they get dirty, just throw them in the washing machine or dishwasher. Baby Babble is a first vocabulary book, featuring baby at the table: spoon, banana, cheese. Baby at play: blocks, teddy bear. Inside baby"s house: lamp, socks, crib. Outside baby"s window: cloud!
