really - I'm sorry but I do find it annoying when people say there is no need for crowning to be painful. That is women's experience and to suggest that of they had done hypnoborthong or been in a different position it would have been better is patronising to me. Also how do you prove this theory? You can't because you can not have the SAME birth in a different way.
Sorry to rant but I found the crowning alwful (very active home births) and there was NO way I was going to just breath my babies out they had to be pushed out by me otherwise i think I would still be in labour now.
Sorry to hijack thread...to answer you question OP...
Scream, puff on g&a, swear, scream puff on g&a, scream, swear, puff on G&a, for a bit of variety swear at your DP/Mw, puff on G&a, etc, etc....
I told my MWs that they really did not understand how painful it was and I was NOT pushing. I got a 'yes dear' reply. They knew that at some point I would realise that to get it over with I would have to push.
