Sorry... just read down to Klaw's post, and I would agree (though I might phrase it slightly differently) about the psychological aspect.
I don't know enough about it to debate the pros and cons of trying for a vaginal breech birth. However, if you feel that you have no choice but to have a CS (i.e. if you feel that the doctors are right to recommend that, and that you are not being bullied into it), then the thing is to get your head around it beforehand, so that you see it as a positive thing and not as, somehow, 'second best'. I had to do this with dd1. Had planned a natural homebirth (which might have been pie-in-the-sky, but it was what I was hoping for, anyway) but had to get my head round a long hospital stay and elective section. (I had grade IV placenta praevia and quite severe bleeding from 27 weeks.) At first, I was very resistant to the idea that I needed the CS and felt very let down by my body and angry and a bit of a failure. But over time (and I had a good 9 weeks in hospital before dd was born to get used to the idea) I came to accept that the CS was the only way that I was going to have my baby and that it would be a positive experience, after all the stress of the hospital stay and the fear that she'd be born very prematurely. I had the chance to talk about the birth very thoroughly with the midwives (and, in particular, with a really superb student midwife who had a bit more time to chat than the regular ward midwives and who told me exactly what to expect and just made me realise that nothing mattered except the safe arrival of my baby) and just to accept that I wasn't going to have the birth that I had planned, but that I was going to be experiencing the birth of my baby, and if that was the way she had to arrive, well... so be it.
This process of acceptance was really important to me. It wasn't immediate, but eventually it did come.
And the birth itself was so beautiful. It was, as I said, 7 years ago, but I can remember as if it was yesterday the moment when the consultant lifted my tiny beautiful, bloody (she had got a bit caught up in the placenta), screaming dd over the screen. It was, without a doubt, the best moment of my life.
Anyway, sorry to have gone on (and on and on), but hope this may help a bit.
