I hope you can change her mind, it's unfortunate but until it all starts she may not know what she can handle if she is not prepared of good with pain. Perhaps you could just give her all the info you can find.
***Shaking head at GP*** what gives them the right sometimes, seems to me they easily scare by saying things & don't want to get caught up in any trouble so always opt for a C/S & that annoys me when some are less educated...or as you say "not the brightest star" LOL.
***hands up*** small pelvis over her, very small - i had a very normal VB, 7hrs, and no epi!!! my doc was worried to but we made it happen & he didn't ever suggest a C/S not once.
