Workman Publishing Indestructibles: Creep! Crawl!
Indestructibles are the 100 percent baby proof, chew proof, rip proof, completely washable, and nontoxic series of books. Books built for the way babies read, Indestructibles are printed on an amazing nontoxic, paperlike material that holds up to endless chewing, gumming, gnawing, grabbing, bending, and pulling. Then, once the books get dirty, parents can throw them in a dishwasher or washing machine to make them clean as new.
