Sorry, I just posted, but I thought of something else.
Our flower girl is the daughter of one of the bridesmaids. And our ring bearer is the son of one of the groom's friends. A little untraditional. So I'm struggling with the "relationship to us" part when you list the wedding party. I know it's usually a cousin or neice/nephew so people usually write:
Jimmy Smith (Nephew of Groom)
But for us, what would I put? "Daughter of Friend of Bride" is a bit much, so right now I just have "friend of bride" and "friend of groom". But is it weird to call a 5 year old my friend?
