I don't know if hypnobirthing is specifically to blame here - rather it's part of a wider narrative that says birth should be this, that and the other, and if you don't achieve that, you've done it wrong.
My labour and birth were shit. My lasting memory of labour, is plodding up and down the river Thames in the middle of December, in the middle of the night with my husband, and having to make the conscious decision not to throw myself into the river, because I was in so much pain, I wanted to die. Not in a hysterical panicked way, but in a considered "it would all be over then" way.
I felt like a wimp afterwards. Other women just breathed better. Others tried harder. Others had the right frame of mind. Others approached it with a more positive attitude. Others laboured "more productively". Other women CHOSE to make the birth a positive experience, why couldn't I have chosen to do the same? Etc. It wasn't until I went to my birth reflection 8 months afterwards, and the consultant was so horrified by how it had gone, that I realised that non of it was my fault - some births are just shit.
And that's the reality. You can prepare, breathe, have the right lighting and music, bounce on your birth ball til it pops under your giant pregnant arse, and sometimes it makes no difference, and the birth is still going to be shit! But that sentiment doesn't sell courses. It doesn't make for trendy memes. And it's not as lovely as the idea that you're a complete goddess, who is in control 🤷♀️
