Query: Great!

My husband and I bought this for our 6 month old daughter because she was having trouble falling asleep alone in her crib. The first night we had it, she didn't cry at all - just looked at the aquarium and listened to the music until she fell asleep. We don't use the bubbles, just the lights and music, which last for 10 minutes. That is usually enough time for her to fall asleep. The big button on the front makes it easy for her to hit and she is able to turn it on herself sometimes. When we went to stay at a friends house overnight, I brought it with us and propped it up next to the playpen that she slept in - it worked like a charm!All in all, I think this is great and is going to be my shower gift to all of my friends who are expecting.
