I gave birth to DS2 on Monday morning after an almost frighteningly fast labour - 31 mins from waters breaking to actual birth. My delivery notes make me laugh, as stage 1 of my labour says 30 mins, and stage 2 (the actual pushing part) is classified as 1 minute!
We were very lucky to make it in time - I literally went into the delivery room and 2 minutes later baby was born, had we stopped at any red lights or if there had been traffic is would have been in the car or in the lift 
So...I wondered, how common is this sort of thing? I mean you couldn't plan for this at all, and I wonder what it means if I have any more...I'd have to move into hospital!
Also, not sure if this is significant, but I ate almost a whole a pineapple on Saturday night - saw the other pineapple thread, so the evidence is there even though I assumed it was an old wives' tale!
