Dotty
I got to 9cms with dc2 before they decided to cut me open., if I had known then what I know now i wouldn't have had another section.
Lulumama is quite right, with my second section they told me I 'had' to lie down and be monitored and I believed them HA.
With my two vbacs I laboured standing up and with my last one I gave birth kneeling/squatting by the side of the bed.
You have to be assertive and don't take any shit. When I went in to have number 4 the midwife told me I would have to be monitored - I told her I was going home and could she provide me with a midwife at home. She was great once she realised that I had very firm ideas on how I was going to do things and with her help I birthed a 10lb 12oz baby with only a small tear and two stitches
Basically I really believe that a positive mind is a must in this case, if you are going to give in at the first hurdle you will end up with another section, try your best and you might get your wish.
Last point here, my overriding feeling about all this birthing and vbac malarky was that if I/we had done everything we could have done to get achieve a natural birth and it hadn't happened then maybe it wasn't meant to happen. In the case of my second section I had trusted the medics, they let me down, I let myself down by not preparing, and next time I knew I couldn't let that happen.
Sorry I waffle, this is my soapbox, I really hope it works, a natural birth seems to be even sweeter after a section (in my case anyway)
Good Luck
