I gave birth in a gigantic hospital (though it was fabulous) that has a "couplet care" policy. The nursery isn't an option unless baby is ill (and maybe the first night after a c-section, I'm not sure). Its very true that I didn't get much sleep (my hubby had a roll-away in the room to stay with us too), in the hospital but I wouldn't want it any other way. I wasn't afraid of any mix-ups, but had a no pacifier policy stated in my birth plan. My son rarely left my sight, and when he did, my husband went with him.
Good luck with your labor and delivery- and enjoy these last few weeks of pregnancy. Sleep, sleep, sleep- though I know I remember feeling like I was going to be pregnant forever!
