hi fensmum....I am she of the piles (and still immensely proud of them )
There is lots of information on p2 of this thread
I took along the relevant bits from the NICE guidelines and the Royal College of Obs and Gynae green top guide No 45.
I was only VBA2C, and had a pretty hard fight to get what I wanted (an intervention free natural birth) and although I ended up with forceps at the end, I was fully in control of the whole thing and nothing was done without me being fully informed.
I would recommend hiring a doula; mine had good local knowledge of the hospitals and their procedures and was able to make inquiries and find out which consultant would be most sympathetic to my cause. thankfully for me that consultant happened to be head of Obs and Gynae so her word carried a lot of clout.
They made a big thing about scar rupture and monitoring but were happy to have me make the decision re continuous vs intermittent monitoring. And after the fuss that was made initially about CFM, when it came to it everyone seemed pretty relaxed about that aspect of things.
there is another poster on here, DaisyMoo who I'm pretty sure had a VBA3C. Hopefully she will see this and pass on her knowledge and wisdom.
I think they key with the consultants is letting them know that you understand the risks involved and that you are willing to take those risks, but that you will remain flexible in how the labour is managed should there appear to be anything wrong.
And at the end of the day, if they get arsey about it, tell them you want a homebirth.....that way they will agree to anything
Good Luck
