After we increasingly had trouble falling asleep with our daughter (3 1/2) - they hibbelte told, jumped up again - we tried it with this classical CD. And it works. Very quietly plays the music in the background and our daughter is quiet within minutes. She listens concentrated and buzzing with ... and after 5 minutes of getting your eyes to this. Just wonderful. Also, I feel much better after this relaxed sleep to soft music. Highly Recommended.
