I think that's a really sensible approach, NoMontagues. My problem was that I fell for all the spiel, did indeed expect miracles, and felt let down and like a "failure" when it didn't work.
I honestly thought that I could cope with whatever labour threw at me. I'm relatively tough - I run fell marathons - and have a high pain threshold. But a 24hr back to back labour was like nothing I could have imagined, and was very much at odds with the "intense sensations" I'd been led to believe I would feel.
Hypnobirthing, IMO, is best viewed as one tool that could be used to help with birth, alongside all sorts of other things, ranging from breathing exercises through to epidural.
Problem is, it's presented as an either/or situation - either you do hypnobirthing,in the water, or your birth is "medicalised." That's not the way it works in reality for lots of people. Hypnobirthing practice was useful for me for eight hours or so of labour. After that, it was not.
Fact is, my son was not coming out alive without an epidural and forceps. As it was, he was pulled out unresponsive. And no amount of positive thoughts and confidence in my own body could have changed that.
This isn't designed to put you off, OP. Hypnobirthing can be useful and in shorter, straightforward births I believe it may be all you need to get through. But it may not be. And if you do go for it, please don't feel like a failure if it doesn't work. I've spent nearly three years feeling shit about my birth experience, which wouldn't have happened if I'd been more realistic from the outset.
