"I really don't understand women that seem to think pain has to go hand in hand with a successful birth"
They don't. But birth tends to be less complicated when women are able to mobilise, which can be difficult when you've had an epidural.
I've had two births without an epidural and one with.
I experienced going through birth without pain relief in the same way I experienced climbing a mountain: it was fucking horrible hard work at the time, but afterwards I felt amazing and had a huge sense of achievement. Nothing like feeling - 'I did all that myself'. Made me feel like superwoman. I know it's not politically correct to say things like that and no doubt someone will come along and accuse me of being smug, but what the hell, it's the truth. And I know lots of other women who've said it too.
Really enjoyed feeling super-high after the birth too. Didn't get the same massive endorphin rush after my epidural birth and feel like I missed out.
"I also really struggle with the school of thought that says that all medical intervention inevitably leads to a 'cascade of intervention'"
Well you probably struggle with it because it's not true. And because nobody says it. Ever. Medical intervention does often lead to a cascade of further intervention. But not all the time.
"I should also add that for every woman who prepares for a home water birth, there is a woman who would rather have her right arm sawed off with a rusty scalpel than give birth without an epidural. Different strokes for different folks, as it should be."
No - for every woman who prepares for a home water birth there are about 15 women who have epidurals.
My personal opinion is that in the current absence of truly humane maternity care across the board - epidurals are a very good thing.
Create conditions which make labour longer, more stressful, more difficult and more painful than it need be and you're going to need to numb women from the waist down, or sedate them with opioids to get through it.
Epidurals are definitely one of the answers to the problems that hospitals have created.
