I purchased this CD about 10 years ago. Since then, I have made five other purchases. My first copy got swiped, borrowed for life, never to be returned. The soothing classical tunes calmed a 3 month old who was fighting sleep with strong healthy lungs. The second copy I purchased for myself. The third a gift to the next baby in the family. It has been my pleasure to keep looking, needing and finding this music CD. I've tried others but did not have the same tranquil effect. There is one song with a woman singing in a coo. My neice of 6 months tries to do the same--and she, too, is another fan.I don't find the smooth transissions between pieces to be disturbing in the least. I highly recommend this to those needinga tuneful means to relax, to those suffering cut-sleep with infants, or those with high strung animals who freak when thunderor windy weather rocks the house!
