We allow 2 persons in the L & D suite while mom is in labor, then after delivery she can have as many visitors as she wants when we get her cleaned up and the room in relatively good shape. If they want a 3rd person, they can ask the doctor and he will usually okay it. My personl feelings are why would you want your entire neighborhood in there watching something spew forth from your "nether regions"??? Maybe I'm just modest, but to me, childbirth is a very intimate and personal event that I only wanted to share with my husband. I didn't even want my mom in there. Go figure. I absolutely hate, hate, hate having to tell people all day long "Only 2 visitors at time are allowed, you need to decide who is going to stay and who is going to leave" it gets very old. And the looks you get after you have to enforce the policy are priceless, like your Hitler or something.
There is such limited space in our labor and delivery rooms and it makes it next to impossible to take care of mom adequately with a bunch of spectators. Also, with pad changes and vag exams, you are constantly sending the visitors that are "unwanted" during those times out of the room, then you have a bunch of people clogging up the hallway which I feel is a major privacy issue for the other moms laboring in adjacent rooms. I wish patients and visitors had a better understanding of all of this. *sigh* If only the doctors would educate the patients about all of this better prior to their patients hospital stays, maybe that might make a difference.
