Prepping our guest list and I realized... my FH has some people on the guest list, former co-workers for example, who have kids and I have no idea how old or how many. He might have a vague idea but probably not specifically.
So, I have a two-part question:
1) Is it rude to invite some kids and not others? I.e., nieces and nephews and kids who we actually know can come, but not teenage kids of co-workers? Our catering is free for under 12 so I really don't mind having kids there, but having a bunch of teenagers there we don't know seems strange, though I suppose most would leave them at home.
2) How to address invitations if I don't know the kid's names? Is it ok to put "and family" and parents will know that that means their children? I could have him ask them for their names, it just seems strange to know someone for a while through work and then have to go, "uh, by the way, how old are your kids and what are their names?"
