I know plenty of people who change last minute for doctors or midwives who will support their VBAC's, breech etc. You have paid in advance for birth attendance, it can be sorted medically. Dont let it ruin one of the few things in your life you will remember forever.

I think for the little time you spend with Obs, and for the amount you spend on them, money is better spent on a private midwife who is there the whole time and keeps your birth normal. JMO
