Well Wander gave you some great advice! Think about the kind of support you'll likely have. What sorts of people do you turn to when you are most afraid or stressed? Who bugs the ever living crap out of you when you are already on edge? That will tell you a lot about the sort of people you will want near you when you give birth.
I will have my husband present, plus one of my closest friends. My husband is very attentive and sweet and good-natured and will definitely be a comfort to me when things get tough. He is also diplomatic and funny so the nurses will like him (and believe it or not, that's very important because if they like you, they'll be more attentive and more cooperative when you say "no thank you" to their interventions). My friend is very knowledgeable about natural childbirth and can be very assertive so that when staff don't listen when we smile and say "no thank you," she will step in and say "didn't you hear them? they said no, no go take a hike," though she's more colorful with her choice of words ;-) She will make a great advocate, and will gladly stand between us and staff if necessary to get them to back off if needed. She might piss someone off, but they won't want to cross her.
When transition hits, I tend to kind of freak out (that's normal btw) and my husband will likely cave at this point and want to make everything easy for me and will be calling for an epidural or some demerol. My friend, on the other hand, will remind him to chill out, and then tell me to suck it up, and remind me it's almost over.
I think they'll make the perfect good-cop-bad-cop tag team for my labor, and I'm pleased with my decision. I would LOVE to have a birthing center or home birth attended by a midwife, but I have way too many complications and risk factors for that. Still, I have managed to have two non-medicated, natural, no-interventions births in hospitals before, and I hope to have a three-peat.
