My FI and I each asked an aunt to be a reader at our ceremony, which they happily accepted. Both of these aunts have two grown children. FI's cousin is one of his groomsmen and my cousin's wife is one of my bridesmaids.
Obviously, our aunts and uncles, as well as FI's cousin and his GF and my and his wife are invited to the RD. My question is if we should invite the other child/cousin in these families. We're all close, they just don't have wedding "jobs". They are invited to the wedding, and they are grown and out of the house, but I don't know...I think I'd feel left out if my mom, dad, and sister were invited to something that I wasn't.
