We all have our limits when it comes to UC birth, I'm sure. I don't think there's a woman alive who wouldn't make an exception for herself during a pathological scenario. Unless the distrust and fear of hospitals and the medical monopoly means they would rather enter the morgue than the ER - and I've met a few like that. I actually feel a lot of sympathy for those women. Once you are in the hospital, you have rights, of course, but it's barely even a chance these days that your rights as a parent and as an individual adult will be respected. You are entering a battle zone, and that's the opposite type of environment a laboring woman needs. That has kept me out of hospitals.
Personally - I would not have been allowed vaginal birth with two of my children. This despite the fact that they needed no intervention. I just had PROM. And I won't be induced for the world. (infant brain damage concerns) So that only leaves me with the knife. My midwife was there for the first PROM and she was willing to risk herself for us, as she had done for others, and that makes her a saint in my eyes. But there are always going to be limits on the variation of normal that midwives will be allowed to accept, and it takes the soul of a martyr to put the mother and child's interests first in those scenarios.
I don't need to be fighting my whole pregnancy and then fighting during birth to stick to my values and convictions about birth. And there's so much authority there, so many ways they can sabotage parental authority, down to misusing CPS to take custody for tests or drugs, even when parent's aren't simply refusing to cooperate, just asking for reasonable preliminaries to take place first. I know one woman (now deceased, as I recall) who's 9th child was taken away for a PKU test at over a month old because she refused to get the PKU test on her baby at birth (actually a UC homebirth) but the test was not done at an appropriate time to get a reasonable result. It has to be done within a short window of time after birth or it is useless. For this useless show of power she had to wait day after day fighting to get her breastfed infant back home. (yes she was in the news but I would have to go digging to find it.) The trauma she suffered... I wonder if it helped to shorten her life.
I only know of this one county in one state to be so draconian about PKU testing - but the point is the same. Doctors and the "law" often trample parents and their babies' rights in nonsensical ways, and generally (my personal observation with friends experiences) this happens when the child comes into the hospital during a birth.
Once you get a midwife involved with triplets, you have a scared midwife, a wise-woman frowned upon by nearly the entire midwifery community and the medical community. If anything goes wrong, anything at all, she gets crucified, new legislation is enacted and the whole community would suffer the loss of her skills and experience. I don't know if I could do that to her... I think almost just out of concern for the birth community I'd have a hard time asking for a midwife to assist with triplets.
