Are the ushers still supposed assist guests to their seats for the ceremony? Because my fiances' BM is going to be my 15 year old brother, will be 18 when we actually get married. And the two ushers will be my other brother who will be 12 when we wed and my friend's husband. I'm just nervous that my brothers won't understand/pay attention on what they need to do. While I'm on the subject, is a 12 year old too old to be a ring bearer?
