The Rock-A-Stack is another classic toy. Your basic ring stacker, with fun beads in the top ring that roll around when shaken. The first thing our 6 month old did when we brought this home was to take all the rings off and play and chew on the base and post, an unexpected source of fun. The post easily (for an adult) unscrews from the base, making a lovely bludegeoning tool. Our son enjoys playing and mouthing the rings and is just now starting to get the whole stacking concept. He also likes to figure out what toys he can fit on the top of the post and into the rings. This hasn’t been quite as big of a hit as the FP shape sorter but it’s a fun toy that’s easy to find in most toy stores, cheap (under 10 bucks), and is appropriate for a wide range of ages, from sitting and drooling to naming colors.
