The main thing is to talk to your ped and your OB beforehand. Since they sign off on your release and the baby's, they are the ones to ask. Avoiding all testing is helpful. If you allow a heal stick for bilirubin or blood glucose, they will expect you to stay if they perceive any problems.
My OB signed me out much earlier than she does most of her c/sec patients because she knew that I had planned for it to be a homebirth and wanted to be anywhere but the hospital. Unfortunately, our ped was out of town, and we had to wait for another doc from his practice to come AFTER he had seen patients all day. There was a 12-hour gap from my release to DS's. Mind-numbing.
