As a "new" mom and an education advocate, I'm very disappointed in the childbirth educator you mentioned. She (or he) is assuming that all first time mom's want the big E; however, not all of us opt for it. Shame on her for assuming such a thing!
With that said, you can go to
www.about.com and find a ton of information on childbirth (go to the pregnancy section) - there's even a childbirth education course offered. I hope this helps!
