I bought this for our son when he was ten months old. He picked it out himself at a store. Since he likes to mimic me, he uses it whenever he sees me using my computer (he has a desk of his own next to mine).
It has three modes: music, sounds/speaking, and shapes/words. There are nine songs in the music mode. My son is three now, and he still loves using this laptop to listen to the songs, and sing along.
