I think 2 nights sounds pretty minimal.
I am also due this December, and have a scheduled c-section for Dec. 18th. It is a Thursday and my doctor told me I would be in until Monday morning! I think that is too long, and I will be eager to get home to my toddler. I am shooting for Sunday afternoon. I think that two days seems a little minimal as well.
Heather - that is the exact schedule that I am hoping to have with my next birth. We are anticipating scheduling the section when I hit 31 weeks for December 29th and I told my doctor that I wanted to be out of the hospital by new years eve. She was fine with that.
