They’re called Indestructibles. They could just as well be called the unstoppables! As in they don’t stop selling (shipping over 1 million copies a year), don’t stop pleasing, and don’t stop filling an essential need for new parents: a book made for the way babies “read,” with their hands and mouths.

Old MacDonald Had a Farm is the E-I-E-I-Oh! classic that introduces baby to the world of farm animals and the different ways each has of talking—the pig with his oink-oink, the cow with her moo-moo, and the baa-baas, cluck-clucks and quack-quacks that fill the farmyard.

The Original Instructibles are chew-proof, drool-proof, rip-proof —and 100% non-toxic. And when they do get dirty, just throw them in the dishwasher.
