I don't know if this qualifies me since DD's labour/birth was induced. But my waters started leaking with her. I didn't actually have contrax or anything, so after 36 hours they induced me.

DS1 labour was LONG. I had prelabour for about 1-2 weeks prior, I have no idea when actual labour started. But when I got to the hospital (just hoping for some panadene and a sleeping tablet, lol) I was told I was 8cm dialated and bub was with us in just over an hour later.

DS2's labour started slowly with light contrax at about 4am which slowly got bigger until he was born at 11.30pm.
