We have it. The first 4 months we used it off and on. But I wasn't sure if it always helped. I used it only at night and we still had nights that she was waking up alot. When we moved her into her room, I used it for a short time. She slept better but think it was just because she liked the crib better than the bassinet. When dd was still in our room and I played it, I found that I slept better with it.
