My FH and I have been together 11.5 years and several years ago I made my niece and nephew promise that no matter how old they were when we actually got married they'd be my ring bearer and flower girl. My niece is 13 and my nephew is 10, and they'll be almost 14 and 11 when I get married this October. Can I hold them to this? I know they're not the stereotypical age, but I'd like nothing more than to still have them do these roles!
