My fiance's niece is eleven years old and specifically asked to be included in our wedding. I suggested to FI that she be a jr. bridesmaid, since my FI's 16-year-old sister will be a bridesmaid as well, but FI thinks eleven is too young and that she would be uncomfortable. She's a bit too old to be a flower girl, and since we're getting married in a really traditional church, there's unfortunately not any parts of the actual service I could delegate to her since she's not a member, like lighting of candles or reading any Bible passages. Can anyone think of any other ways I could involve her in the wedding day? I don't have any siblings and never really spent much time around children, so I'd really like to start a good relationship with her since she is my only (and first) future niece.
