Not to sleep; but as I had a private room he was pretty much able to stay as long as he wanted. Most of the nursing staff had no idea as to whether he was around or not (they were very hands off with me; really only seeing me during the day and only at night if I pressed the buzzer).

He only left really so that he could sleep before going to work (he worked up until I left hospital). I didn't mind - I gave birth where I worked, so had MORE than enough friends to keep me company... :lol
