I like the "leave your children at home" one. We had so many kids come visit in hospital and as soon as we got home and I hated it. They were loud, demanded attention and would have been rough with DD2 if I hadn't have stepped in.
These were relatives too haha but it was just too stressful.
We also had family demanding to see DD2 in NICU! I couldn't believe it. When I said no, they tried on their own (was on a different floor). Luckily only parents were allowed so the nurses kicked them out.
