I have a very small team at work (only 4 of us), and we're all close, so I'd like to invite my 3 coworkers and their significant others. Two of them have teenage children that I've never met. We are inviting children to our wedding, but all of the other children are young (under 4) or infants. The only other teenagers would be my cousins. Is it rude to not invite my coworkers' children?
I don't want to split up the families, just thinking that if I was a teenager I wouldn't have fun going to a wedding for someone I never met. Their children have stayed home alone previously, so they wouldn't have to hire a babysitter. I remember my parents going to coworkers' weddings that we weren't invited to, but never thought about if that was rude or not.
