I did Calmbirthing when I was pregnant with DS. I highly recommend it. I'm lucky enough to live in a town near the creator of Calmbirth and he is still doing the courses. He's amazing but I'm pretty sure he trains all the other Calmbirth trainers himself.

I wanted a drug-free labor and birth and for 12 hours that is what I got. I used the Calmbirthing techniques and I can honestly say I loved my labor. Then after 12 hours it ended in an emergency C-Section but the Calmbirthing techniques were useful for that too.

It's definately something worth looking into. If you Google it you will find Peter Jackson's website with alot of information.
