My daugter loves this toy!! There are 3 levels of play according to age. Stage one plays a montage of music, with no interruptions. In stage two, music is ativated by pressing or kicking the piano keys. In stage three, the piano keys have their own tone, and baby can make up a song of her own. Whether it is set in her lap or strapped to the side of her crib, she gets a "kick" out of the Kick and Play Piano!
