So we're getting married in December and STDs just went out. Addressed correctly to Mr. And Mrs. Mom and Dad Cousin. No daughter. We aren't planning on inviting kids to the wedding because we're not really kid people. Daughter cousin is about 6yo and a hellion on wheels- not a kid I'm a fan of even if I liked kids. Now I have informally invited my FSIL's son-on-the-way, because, you know, he'll be like 3 months old at that time, and she's traveling from a ways away. But that seems like a pretty obvious exception.
However, of course, Mom Cousin texted me tonight and said "Dad and Daughter and I can't wait to come to the wedding!"... Um no. Now this family has a tendency to bring uninvited guests to things- Mom Cousin has repeatedly brought Grandma Cousin (that is her mom) to family events (like Christmas Day and small family cookouts) to which Mom, Dad, and Daughter were invited, but Grandma certainly wasn't. So at this point I'm trying to figure out if there is a polite way to say "Daughter is not someone I want at the wedding" because really, three hours of peace would be great (please stop running around and do not hit your father in front of me).... But I also have a small, close family that recently experienced loss (the connecting piece between Mom, Dad, Daughter, and me), and yes, the wedding has come up a good bit in front of Daughter (I'm an only grandchild, so there's not a lot of weddings going on).
Do I suck it up and go "oh goodie I can't wait to see you all there"[dammit] for the sake of many years of family peace, or do I politely say hey we're having an adult only thing (no good excuses here, it's a cake-and-punch afternoon reception with a glass of champagne all around).
