FH and I both have a child - him a daughter and I have a son. His daughter will be 17 and my son will be 18 at the time of our wedding. I am very close to my son and his daughter lives out of state - we want to find an "adult" way to include them in the ceremony. My son is "giving me away" which is very symbolic to us because of our closeness and the fact he is leaving for college a month later; his daughter is one of my bridesmaid.
For example, with smaller children, I've seen them presented with a piece of jewelry, multiple candle/sand vases...Do any of you have teenage children? Did you do anything "special" for them?
