No. F em

If they had a tendency to make derogatory comments around the child or things like that, absolutely not. otherwise i don't see any reason to stop them from seeing them. Civility is very easy to do as long as people can be mature adults.

No I would not, because my children are good kids and I don't want them to be influenced in bad ways by my relatives or had me thrown under the bus in any way.

Nope, but I would let them know in advance and I would tell my kids to stay away from them.

Depends on the reason also the age of the child if they can control themselves from saying things in front of your child
