Thanks for those links Trillian - they are great.

If it were me, Numa, I personally would have to give the vaginal delivery a go, and then if it didn't work out in the end- then so be it. It may seem easier just to opt for a c/section and save dissapointment later- but truthfully, I think you would always wonder 'what if..?' - know what I mean?

I had a labour which spanned 4 days (I was determined to have my baby at home in water without drugs), but on the last day (at only 3cms dialated) I was too exhausted so opted to go to hospital to speed things up and ended up with an epidural, episiotomy, etc. I was disappointed that I didn't get the birth I had hoped for, but my saving grace was that I ended up with a vaginal delivery in the end. Looking back, it was the only aspect of the whole labour process that I was really happy with.
I know not everyone feels this way about vaginal delivery, but I just think that, no matter what your views on birth are- nothing should stop you from attempting to acheive the ideal. Just don't consider it a birth 'plan' - more of a birth preference. If you do not get your first preference- you can re-assess and take it from there.
