as an anesthesiologist I have witnessed thousands and thousands of births and all are unique and special for those involved... don't worry about passing out or puking, happens all the time
epidurals are much better than advertised, friends will tell you all the horror stories on how it didn't work, wore out or was painful but in the right hands is a safe, quick, painless and very effective procedure.
I have seen deliveries that were videotaped, webcasted and photographed beyond belief, have seen them with everybody ranging from grandpa and kids, neighbors and drinking buddies in attendence (one time 14 people were in the delivery room!!) but by far the best times are witnessing first time mom and dads see their new baby come into this world and into their arms.
Enjoy the whole experience, believe me you will never forget it!!
