So I have 3 real "candidates" for flower girls for my wedding. My daughter and my two younger sisters. My daughter will be 2 1/2 and my sisters will be 5 & 10. First question is my 10-year-old sister too old? The second question is, is my 2 1/2-year-old too young? Third, would having all 3 be flower girls be too many? The wedding will probably be between 100-200 guests.
