This was purchased for my soon-to-be 7 month old daughter. She really loves the music. The volume was a bit low making it hard to hear if there are other sounds happening at the same time. She activates it by crawling on it, pressing the pictures, and the big play button. She loves dancing to the songs. My 11 y.o. will also play Mary Had A Little Lamb with her on it. She really enjoys it!!
