What were your hospital rules when you delivered?

I’ve come up with some pretty basic rules; don’t come if you’re sick, no kissing the baby, don’t show up without asking, don’t overstay your welcome, don’t post pictures of the baby without asking, etc. My big rule is going to be no kids. I know this is gonna upset a lot of my family and I feel bad but I’m not sorry. Is this an unreasonable rule? Most people I ask say that it’s a normal rule but I’m nervous about it. What should be the age limit for the “no kids” rule? No one under 10, 12, 15? What would you say?
