Approx 10 mins 2nd stage with ds1, back to back. Didn't take a copy of my birth notes so can't be 100% sure, it's was quick enough to surprise the mw!
No pushing with ds2, contractions did it themselves as I was kneeling up. On my birth notes it's says vertex visible 11.25, delivered 11.28 so I'm guessing it was recorded as 3 minutes. I only had one mw present, so I'm guessing it took her by surprise lol.
Small babies helped (7lbs &7lbs5oz) but RLT played a role I reckon!
