L.A.
I had a midwife with my first baby and an ob with the second.
I LOVE my OB. I wanted so badly to enjoy my experience with the midwife, but in the end I chose an OB that was comfortable with a natural birth experience the second time around. The hospital we delivered in has pools, you labor and deliver in the same room, you can walk around, etc. So this might be a question of just finding the right professional and facility.
However. If you've always wanted to give it a try, try it! Be sure to meet the back-up doctor and know the route to the hospital. Personally, I chose to use the birth center instead of a home birth because I wanted the separation and rest that comes with not looking at all your stuff while you labor. I loved running around the birth center butt-naked and dancing my way through the contractions.
When the birth hit some roadblocks, however, I found that my midwife didn't have the technology on hand to determine why we weren't delivering. I ended up having a c-section. There's a part of me that wonders if we'd had that extra technology we might have been able to coax my kiddo out. My midwife didn't want to do any sonograms after we passed our due date so we didn't know that my daughter was in the wrong position for a vaginal delivery and thus missed the opportunity to get her turned in time.
I'm not wanting to talk you out of anything or into anything else. This was my experience. I'm very glad I tried both, even though I ultimately had two c-sections. I still support a woman's choice to have a midwife or an OB. I strongly feel like it's a question more of a professional you connect with and trust than of the letters after the person's name.
Also, my OB was the one that delivered my second baby and I met all of her practice partners in advance in case I went into labor early and she wasn't on call. So just keep looking until you find your magic person!
