Unmedicated birth of twins, one breech, and it was a "high risk" pregnancy. (
sounds like bragging, I know, but such things can be done in a hospital, and happily!)
If you're uneasy about giving birth in a hospital, you can either change the venue (a birthing center is a good option), or do everything in your power to make the birth you want possible. If you want to be truly ready for an unmedicated birth, then that will take a lot of dedicated work on your part and on your partner's part, too. Whether or not you want to try Bradley classes (which have a GREAT success rate for non-medicated births in hospitals), you will probably want to do a lot of reading on the details of birth and, if you want the odds in your favor, hire a doula.
Between educating yourself, taking Bradley classes, and hiring a doula.... well, let's just say you'll have every possible base covered! Nothing's a guarantee, but effort never hurts!
BTW, I think two useful books are "The Birth Partner" by Penny Simkin and "The Bradley Birth" (title might be off??).... The birth partner is a well-rounded book, covering the plus and minus of every birth option. The Bradley birthing book is very militantly against using pain meds, but some of the mental exercises in it, and the descriptions of labor "types" are SO useful.
I'm sure others could give you great recommendations, too!
