The VTech Crazy Legs Learning Bug is a great learning toy that will grow with your child. When we first got it, my daughter was a year old and liked it for the music. As she got older and started walking, she began to use it as a pull-toy and would drag it by the included string. Now that she's a bit older, she's trying to learn the puzzle function. The Crazy Bug is really many toys in one. It teaches the alphabet, counting, types of bugs, shapes, colors, following directions, and music. When used as a pull along toy, it sings and the top bug twists back and forth. I don't think my daughter has used even half of the things this toy can do yet. My only complaint about this toy is it is too easy to turn on. We always turn it off to save on batteries, but the button can get easily knocked in the toy box. So I recommend keeping this toy out of a childs room so it doesn't go off accidently and wake them up. I do think this is a great educational, and fun, toy for kids that will last them a long time.
