I was in for a few nights following a difficult birth. No big drama but they had to monitor me for a few days. We were in a single room and had fantastic care.
Dh would be itching to leave by 7ish each night and would come back at about 11am the next day. As the care was good this really didn't bother me at the time but chatting to other mums it seems he's a minority.
If your partner was allowed, did they want to stay? Were they sad if they couldn't? Did you want them there?
