My fiance has 2 nieces, ages 5 and 7, and I have a 6 year old niece. My niece wants to be the "only" flower girl, so I was trying to make her "special" by having her be the only one to throw flower petals. And have the other two carry some sort of flower wand. My fiance doesn't think this is fair (and I kind of agree), but I've already told my niece she would be the only flower tosser. What should I do???
