My first was 37 hours, back labour, ARM, syntocin drip, ventouse delivery, "stargazer" baby, 9lb12oz! She was 4 days before edd.
Second started with waters breaking, 10 hours in total, no interventions, he was 10 days early.
Third was 12 hours but an induction. Simple delivery, apart from the prostin gel no interventions. I was 36+6 weekes but very unwell with kidney problems caused by the pregnancy. She was fine but I'd been air-ambulanced out due to the kidney issues.
First labour was awful compared to the 2 subsequent ones, I felt like I birthed "well" all 3 times. Never needed an episiotomy, never had an epidural, one instrumental delivery but given her position I'd no option, only had opiate pain control the first time, had G&A in the second and third.
There's no way I'd compare my 2nd/3rd deliveries to my first. Though by the time dd1 was born I was so exhausted I don't remember anything much!
