I know in most cases the first child takes a loooong time for labor, but not always. My son was born 7 1/2 hours after I thought something just might be going on. I went so fast I didn't even get my medicine like I asked for. And I have a friend whos second child was born in 20 minutes. 20 minutes, meaning she felt a small twinge, and went into full labor, couldnt make it to the hospital in time.
So hopefully you made it in time to get to her bedside. Gratz and all
