Childbirth without modern effective pain relief- really is traumatically painful. It isn't fear that causes women to suffer pain - that is just propaganda by the natural lobby and very cruel because it makes women feel bad when things go wrong.
Did anyone watch the lovely birth on US OBEM by the midwife? Totally peaceful, joyful, no groaning in pain or anything. Was it natural? Not a bit - spot the epidural line in her back!
I think the problem is that OBEM by showing the reality is scaring the natural birth believers. It is making them feel they are losing control of the agenda. Actually, for women, that is a good thing. Some women do have relatively painless births, good for them - they are lucky.
A documentary is a documentary. Yes, of course they will have edited the highlights but what they recorded really happened. They didn't rehearse it.
The natural birth lobby need to open their eyes to reality.
