Since my first (& only) niece was born, I knew she would be my flower girl in my wedding. Now I'm engaged, planning my wedding, and my (now) 10yr old niece informed me she really wants to be my flower girl, much to my delight. My fiancee, however, thinks she is way too old, and thinks his best friend's 2yr old daughter should be our flower girl. His best friend is his best man, however, I've only met him once (3 years ago) and I've never met his daughter. My fiancee has only met my niece once, but that's only because they live in another country.... Advice needed???
