It is my understanding that for the rehearsal dinner, the people that will be doing something at the ceremony are invited to come practice. That means parents (readings), groom's siblings (groomsmen), bridesmaids, musician. My question is how about the flower girl and ring bearer. Do they need to be there too? Our flower girl is my FI's niece. The ring bearer is my cousin's son. If so, the parents should also be invited, right?
My second question is this. Two of my Fi's brothers have children. Each brother has two children. If both parents will be at the rehearsal, do we need to also make plans for all the children to be there as well? My cousin also has two children, but only one will be in the wedding, do both children need to be there?
I just want to make sure we don't miss anybody, and that we don't invite someone that is not needed.
