I've purchased the other Rainforest mobile (rainforest dreams - it has soft toys and a light show attachment). Although it has yet to be uesd on a baby yet...I've given it a test run...the volume control has 2 settings so it can either be very soft or a little louder and the music has 3-4 lullabys and also a 'rainforest noise' setting. I think it's really cute and haven't regretted the $$$ on it. I love the rainforest range! (also bought the play gym!)
