its just luck,i grew up in a third wolrd country,all these intervensions you talk about,they do not exist in my country,when a woman is pregnant,she is never told about the actual pain of childbirth,it is seen as a natural thing for a woman to do,
my mum had 8 of us,7 vaginally but my brotherwas delivered via c section,my mum had lost 4 babies before,she gave birth to them dead,because after labouring for hours,she couldn't deliver,and they died,di she plan the others?no,just luck
my sister has 3kids,all delivered vaginally,she also lost one baby bcoz of the same reason with my mum,did she plan anything?no,just luck
i got pregnant,didn't think there was any other way other than natual,after all thats whats done in my family,i went 14days overdue,i was not dilated even after being induced,got the epidural,nothing helped,i had to get emcs bcoz the baby's heartrate dropped,did i plan on this?no,i was just unlucky,i was only glad when my baby was placed in my arms that she was alive and i was ok,,i did everything to prepare,running up stairs,exercising,reading,you name it,next time i am doing NOTHING bcoz everything will fly out the window when the actual labour starts,sorry too long
