To help keep our #s down (for financial reasons and venue restrictions) we have decided to only invite our families out to 1st cousins. So, our first cousins are invited, but not their children. However, my first cousins (invited) on one side of my family are the same age as my 1st cousins' kids (second cousins? first cousins once removed? i never understood that stuff. anyways, they're not invited) on the other side. We made the cutoff to simplify things, but I worry my first cousins will wonder why their kids are not invited, when there are other similarly aged children there.
