Helen31, the link between bonding and pain is clearly marked as 'emerging research' in the prof's paper and referenced...the paper referenced gives a speculative association only. He's not teaching this.
peppamum - you're misreading my post, I think. Some women aim to give birth without pain relief for whatever reason (in my own case it was to avoid the risks of an epidural going wrong, together with a desire not to have my lower body numbed which for me was a horrible prospect - prob a personal thing - along with a desire to be in control myself and not medicalised). This is a challenge. It is increasingly difficult to meet this challenge, as the prof describes, in a maternity service which doesn't listen much to mothers and where care is fragmented and where birth is greatly feared.
When that challenge is met, despite the obstacles and barriers, why can it not be celebrated?
If someone does not set themselves that challenge, but (maybe) sets themselves a different one, lets say, to have a vaginal birth instead of a repeat section, or to breastfeed without bottles, then they can have that celebrated as well, can't they?
None of these examples - birth without pain relief, VBAC, bf without bottles - is a matter of purely personal choice. There are elements of chance and luck of the draw in all of them. But they do all the same sit in a cultural context that makes achieving them more difficult than it should be.
Can you see this has nothing to do with denigrating mothers who don't have same aims, and why sneering at the aims (with an ironic 'whoop de doo!') is so unpleasant?
