I'm having a hard time with how to indicate that certain members of a whole family have plus ones on my wedding invitations. For example, my aunt and uncle have three kids in their teens and twenties, all of whom are invited. All three of the kids are in serious long-term relationships and I want them to be able to bring their significant others, but how do I indicate that all three of them have plus ones if I'm sending the invite as "Mr. and Mrs. so and so and family..."? I guess I could send separate invites to my cousins at their own addresses but I'm pretty sure only has moved out of the house, and the other two are in college and still live at home. It's probably a very easy solution- I just don't know what the etiquette is here! Any suggestions would be appreciated
