Here's the abbreviated version...
The night before mom was admitted into the hospital to have me, I tried to break open the sack of waters to get the show on the road. Mom noticed a small leak and told dad it was time to go to the birth center's triage for a check-up. After the doctor examined mom, he said: "nope, not leaking amniotic fluid..." and sent us on our way home.
The next day mom and dad went to the scheduled post-due doctors appointment and the ultrasound tech looked at my position in mom's belly and also measured the amniotic fluid surrounding me. Sure enough it was really low. Mom told the doctor as they were talking in the examination room and the doctor said: "looks like you're having a baby today! I will call the birth center and get you admitted right away. Just walk across the courtyard to the registration desk, they'll get you a room and begin the induction process." Mom and dad were a little shocked because it wasn't exactly how they planned to be admitted to the birth center, but also they were excited that I'd be on my way soon.
Mom's a good sport and has been healing from a level 3/4 tear.
