I agree with PP a simple birth plan and a sign in the basinet are all you need. If they push you, re-iterate what your plans are. Remember you and your LO are patients, and you have rights as a patient. For example, if your OB orders up an epidural and you didn't ask for one . . . you don't have to take it! (Though you may be planning on one which is fine too ;-)
I would joke with my family before I had DS this July that I was going to be kicked out of the hospital. I had my baby in a hospital going for the Baby Friendly certification which made me feel great about my choice to birth there. http://www.babyfriendlyusa.org/eng/index.html They have Lactation Consultants staffed but I still can't believe how many of the Nurses wanted me to use a paci, one even told me before my milk came in that my baby must just be sucking for comfort and I should give him a paci so he didn't use me as one. That was at night, the next day I mentioned that to the Lactation Nurse and I asked about the Baby Friendly certification they're going for and how on earth offering a paci fell into that. She was pretty ticked and asked me which nurse so I'm hoping she addressed it. It was plain as day in my chart that there were no pacis, we'd be rooming in, and absolutely no supplementation.
So, make your plans clear and stick to your guns, if a nurse is driving you nuts get the charge nurse and say you want another nurse assigned to you and state why, they aren't being observant of your wishes, etc. My husband is Nurse and this happens occasionally, he made sure I knew what my rights were as a patient when we entered the hospital. He explained Nurses aren't offended by this, if a patient wants someone else they get them.
Do what you feel is right, and don't let anyone make you feel bad or try to sway you another way. Take a look at the baby friendly info and make sure your PEDI and OB/Midwife are supportive of your wishes too.
