I used this CD for the birth of my first child and it actually worked! Even though I was really nervous at first, I made it through 3-1/2 hours of labor without any pain medicine (It's only fair to say that I used Lamaze also).My husband is a psychologist and when he listened to the CD, he said he'd heard about some of the hypnosis stuff and this type of psychology called NLP that I think Dr. Zelman used in the program. It's powerful stuff. The quality of the recording isn't good at all (I had to take off a star because of it) but the techniques were so good I was able to overlook the bad sound quality. In short, it's worth the 15 bucks to avoid hurting your baby with sedatives but don't listen to the ocean part when it's time for "American Idol."
