... My wife thinks it works :-)

My wife thinks our daughter (about 1 year) takes the CD to good.
We play the piece when it comes to bed "to come down".
I think: Mostly it works.
AC / DC has not been successful.

For me it was when Dad was important: No more annoying whining !!! But as I always take my room for improvement, gets the CD 4 stars. 5 star there when I start the music, and she sleeps now until the morning at 09:00 clock by ;-)
