Hypnobirthing. What is it?

Hypnobirthing. Giving birth while under hypnosis? That doesn't sound right. So what is it?

Hypnobirthing is a technique that helps mom focus intently on the labor process and understand how the birthing muscles work in harmony. According to Hypnobirthing.com, this method "teaches you that, in the absence of fear and tension, or special medical circumstances, severe pain does not have to be an accompaniment of labor."

Celebrities, most recently Jessica Alba, have embraced this trend in natural birth. Completely awake, it helps you relax and be aware and totally in control of your body. Birthing centers and hospitals have classes that teach these self-hypnosis techniques.

Relaxed and calm. Isn't that how it should be?
