I agree with infromed choice also, but I am more towards low risk women trying for a normal birth. Having recently been involved with a shoulder dystocia on lady who had a previous shoulder dystocia due to big babies both times, I however, wonder why the hell this lady was ever allowed to get to term +8, and this time for me I believe a c-section should have been offered, this is also due to the effect the trauma had on her first time around.
I personally had a section with my first and was offered it with my second, I refused and chose a vaginal delivery for him and my third. There was no medical reason for me to be offered a section, I had it first time around due to a placental abruption and therefore an emergency and no choice, (unless I wanted to let both of us die that is ..lol.)
