When I say positive I mean not an instrumental delivery, not mentally traumatic and didn't result in a bad outcome for baby or a severe perineal tear.
I'm 36 weeks with no.2 and my first was a 30hr labour that gave me birth trauma due to lack of good pain relief. 2hrs of pushing followed by a ventouse delivery and episiotomy with a not-straightforward recovery and a permanently weakened pelvic floor. As far as I know DD wasn't back to back at any point. Midwife thinks this one is.
