Baby number 1: 0 minutes. It says so on my notes, I love that they filled that in.
Baby number 2: my first labour - 45 minutes from when they said "oh no you're in labour" to when they pulled him out of my tummy. . Do I win the shortest? Probably not,haven't read the thread. Bet there is someone who managed a vaginal birth in half an hour...
Next baby - hmm shall I have a vba2c? nope, methinks it will be nought minutes again!
