I wish I could count mine from first sign of labour, 344.75 hours with Brendan and 8+3 weeks with Tristan. I was having contractions, but they had me on drugs to stop them and all the drugs did was ease them off not the pain. With Brendan I wasn't in a lot of pain but with Tristan I was in agony for the whole 8 weeks. I actually only count it from when I started getting them regular though (once the drugs stopped) so for Brendan I count it as 20 hours and 45 mins and Tristan 10 hours.

Official labour times, as per hospital records which records from 4cms dilated, are:
Brendan:
1st stage 11hrs 55 mins
2nd stage 20 mins
3rd stage 5 mins

Tristan:
1st stage 7 hours
2nd stage 34 mins
3rd stage 7 mins
