I've just found some great links on natural childbirth and epidurals, and I've just got to share them!!
First, on pregnancy.org, there is a whole section of Tips on Hypnobirthing. I've just been reading it for the last 1/2 hour, and it's fantastic. For some terrific information on medical procedures frequently used in childbirth, pay special attention to Tip #9: Your Birthing Choices.
Finally, I just read a great article on Epidurals. My reaction is - wow. :)
