How does this baby stack up to the original 1963 Rock-a-Stack toy? Well, for starters, it's designed for babies with tactile elements on each ring that little ones will love getting their hands (and mouths) on. There's a soft fabric ring, a smooth plastic ring, a ring with bumpy textures and another with lots of textured ribs. A sweet puppy, with soft fleece ears and bumpy spinning collar, tops it all off. And the bottom is a roly-poly base that jingles as baby bats it back and forth. This iconic toy now rocks on for wee ones - and offers fun stacking play as baby grows.
