How old is too old for a ring bearer & flower girl?

11 is an age where it is kinda weird to be doing it so the 9 year old would be a good age for a flower girl and the 13 year old can be a junior groomsmen. Then just find a cousin or a friend's kid or something to the ring bearer. My sisters fiancee had a junior groomsmen who was 13 and my other sister had a flower girl who was 10 and you could have a flower girl and not a ring bearer. (most people don't put the actual rings on the pillow anyway) so just have the best man give him the rings and the soon be 9 year old can be the flower girl and the soon to be 13 year old can be a junior groomsmen. I REALLY hope this works out. I hope you and your soon to be husband have a long happy marriage! God Bless
