Query: good option

The only reason I'm giving this four stars is that it doesn't have a continuous play option. We stopped using this for white noise and bought the First Years Nature Lullaby Player instead because it plays constantly and won't shut itself off, since our baby wakes up if the white noise goes away. Otherwise, very cute, very entertaining and easy to use. And for the reviewer who said it was too loud--the volume control works well for that problem.
