My 1st labor was very short and sweet, I came into the hospital with a pain in my side and 7cms already dialated, I didnt even know!!
4 Hrs later my daughter was born, waters didnt break (nothing)!

2nd labor took 14hrs, and that was pure hell- my son was pushed out from when I was 6cms, I needed him out.

But generally they are quicker than the first-didnt mean to scare you!! LOL 8-[
