Query: a staple

We started playing with this toy at around 7-8 mos. The thing I like most about it is that we have another Fisher-Price shape sorter and the shapes are interchangeable so instead of only 12 shapes we have double that! Kate likes banging the blocks together, dumping the blocks, talking into the container, etc. It's not glamourous but a good basic toy.
