I read from the knot that it's 4-8 years old, but I have been hearing different things from people. I regretfully told my mom that I *might* as my brother's daughter to be my flower girl, and my mom "accidentally" told my brother about it before I could ask my bro/niece formally. As if it weren't bad that my mom slipped her tongue, my brother's response was that his daughter is too old to be a flower girl. The girl will be 7 on my wedding day. Another young girl we would consider is FI's cousin, but I think she'll be 10 years old. She's just so adorable, though. They are the two girls that we are closest to and I am thinking of picking one of them, or we'll have to just skip the flower girl idea all together.How old is your flower girl, and how old do you think it's too old?
