I have a friend who had baby at home with a painkiller-free labour and midwife and doula. It took 7 hours and went well. Because of this, she remains absolutely convinced (she's a woo fiend in general, it's not just childbirth related) that every woman can do it if they avoid nasty male doctors and harried midwives, do yoga, and 'get in the zone'.
If they have failed (and a neighbour's home birth went sadly wrong, but she ignores this) it is down to the woman's lack of education, her sheep-like attitude to the male-dominated medical profession and her fear of her own body.
Of course, nothing to do with her luck, her physical attributes, the baby's position. And of course she ignores the unusually high attrition rate humans suffer in childbirth compared to other mammals owing to how we've evolved.
She has no idea how patronising she sounds.
I'm genuinely pleased it went well for her. But she fails to see she is guilty of unwitting confirmation bias (as most woo fans are) because it went well for her, she did it correctly, and others effectively 'failed' to get into the zone, 'listen to their own bodies'.
If you want scaring, check out the perinatal (not infant mortality, which is the usual metric) rates in Netherlands, which has half of births out of hospital. Just to put what childbirth can put us through (and we as a species are unique in how dangerous it is for us) into perspective.
