Extended family.. how far?

I just wouldn't invite their kids. I limited it to just first cousins, because there was no way I was inviting my (40!) second cousins all under the age of 13.

Also, how do I address the invitation if I’m limiting it?

I have a hugeee family, so I just limited the guest list to first cousins and immediate family!

When addressing i’d write out your cousin’s name and her spouse’s as well if she has one. If not, then just her name and on the RSVP i’d write “we have reserved __ seats in your honor” and write in the number. Hope that helps!!

We drew the line on second cousins, we only invited one because my husband went to her wedding. It’s fine to only invite the adults, just address the invite to them specifically. Also just wanted to say your second cousins children are your second cousins once removed, not your third cousins!

If you're having children at your wedding, I think you should invite the ones that are still under 18 and live with their parents. My FH has a cousin with 5 kids. 4 are still children, but one is an adult, engaged, and has a child. We see her children often but hardly see the adult child. I'm considering not inviting him. Or hoping he just won't come.

I wouldn't invite any of them, but I think this is an all or nothing thing. You can't invite some siblings and not others.

Completely agreed with all here - just don't invite the kids. And definitely make it clear that it's an invite for the cousin and spouse only - whether that means writing in a 2 on the physical RSVP, or doing online RSVPs where the names are pre-populated.
