I have all of the people picked out to be in my wedding party. The trouble is deciding if my BFF of Sister should be my MOH. I want to pick my BFF because I know she wants to do it and will have the time to and not complain about what I pick out and want to do. My sister has a 6 month old who will be one of the FG. But she had mentioned to the BM that she will be walking with him down the aisle. Is it tacky to make one a Co. MOH? I will be having 3 brides maids 1 junior brides maid and 2 flower girls.
