I'm sorry this is off topic, but your SN is hilarious.
I delivered my first naturally at a hospital...I guess my biggest suggestion would be to labor at home as long as possible. I'm not sure about how your hospital will be but the one I delivered at puts all laboring women on fall precautions, which meant I wasn't allowed to stand up at all. Which standing and walking helped me a lot through my contractions. Also to make sure you talk with your doctor about your birthing plan, take a tour of the hospital so you know where to go, and if you can, pre-register so you're not filling out a bunch of paperwork while you're in labor.
