I already know I want my goddaughter to be my flower girl and we would like my fiances nephew to walk with her, he's only a few months older, but they will not even be two by the time of the wedding. Do I need another option instead of walking down the aisle like a wagon or something or do you think they'll be able to do it? The flower girls mom will be one of my bridesmaids, would it be rude to ask her to walk behind the two still in her dress and everything?
