I am in a similar situation but my FI has 2 boys, 13 & 14. He has two groomsmen and i have one bridesmaid and a man of honor. Yes this is going to be interesting!! Anywho, we have thought about having them walk me down the aisle, but my mom really wants to do that. So we have decided to have an odd number on his side. There will be 4 (including the two boys) on his side and then 2 on my side. We may split them up while we stand there, but honestly it is a unique wedding anyways...does it really matter?!?
