My births were 3 1/2 hrs and then two at 2 1/2 hours. It's weird because my first I thought was way too quick at 3 1/2hrs (I went into shock after it but I think that was more because I went from 5cm to baby in arms in 50mins) but then both my next two labours where perfect lengths for me - I loved them all
Such a birth junkie, LOL!!!
