If you want to get a toy for a baby — and assuming this one isn’t coated in lead — I highly recommend this one that they currently are selling of at Toys “R” Us. It’s the Mozart Magic Cube and it:
inspires creativity and interactive play. Plays 8 Mozart compositions. Mozart Magic Cube teaches how sounds combine to form musical masterpieces. Add and subtract instruments at the touch of a button!
It’s alot of fun, regardless of whether or not you are 6 months or 600 months old. 🙂
