Discussing labour with my midwife the other day she mentioned that they "allow" women to only dilate at a rate of 2 hours per cm before intervening.
I'm planning to argue with their protocols on some other issues but I was wondering about this one. I was under the impression that you might not dilate at a regular rate right through labour, so is the 2 hours rule based on safety or is it another rule for the sake of having rules?
