My sister was born about 10 days over due in Whangerei, NZ - all natural.
My sister was stillborn at 21 weeks in Whangerei NZ, so induced and I'm pretty sure there was painrelief involved. Mum didn't handle it well, she was bleeding and her veins collapsed and they had to call a code blue. They are surprised even now that she survived. She ended up needing a D&C after my sister was born, as there was retained placenta.
I was induced 10 days early in Horsham VIC due to suspected IUGR (how ironic, now that I think of it.... DD had severe IUGR), I'm pretty sure Mum had some pedadine with me. Turns out I wasn't that small, 6lb 12oz.
Brother born all natural with no pain relief in Nhill VIC. Mum was really sick with the flu, so she struggled but managed to do it natural and push out a 9lb baby, he wasn't breathing and needed a puff of oxygen, and was OK
Brother born in Nhill VIC. Mum wanted to do it natural, but for some reason they gave her pethadine without asking. My bro was born facing up, and as he was delivered he pee'd everywhere.

My Mum did a great job.
