I've only had one labour but I hear 2nd labours are much faster. When I was in hospital, a midwife was talking to me about something (This was during my stay after giving birth), and another woman was in labour. The midwife said to another, "Let me know when she's fully dilated and i'll come in." But it never happened because by the time they came and got her and she went back to the labouring woman (and its not as if she was far away), baby had already come out lol. I'm sure you'll do great and it'll be a wonderful experience!
