How old is too old to consider one to be a flower girl... My cousin is 6 years old now, and our wedding date would make her about 8... My mother thinks that this is too old to call her a flower girl, and that we should have her be a junior bridesmaid. I really wanted to have a flower girl in the wedding, but have no one else in the family young enough to do so... Is 8 too old to ask someone to be a flower girl?
