Can't help you with a study I'm afraid. I do know that with #1, I had him around 1:30pm and I think we left the next morning. We were first time parents though, so the overnight stay while I figured out breastfeeding was good. We were so ready to leave in the morning though. Hospital is boring. Don't forget your DP is allowed to stay overnight too, you might want to sleep and he can get up to bub - that's if your DD is getting looked after. And other babies aren't so much of a problem in the FBC.

As the others have said, see how you go. If you birth in the morning, I can understand wanting to sleep in your own bed that night. But who knows, you might give birth in the late arvo, and they won't discharge you overnight I don't think, *I think* they like a paed to see your bub first, and they're mostly around in the day.
