We have had trouble with our 2 year old staying in bed. She seems to think night time is a good time to bounce off the walls :) We started playing this CD and within 2 nights she was sleeping soundly without trouble. She shares a room with her 4 year-old sister who loves the CD as well. She will ask to have it played every night. It is very soothing background music.
