So my fiance and I decided to not invite people under 18 to the reception but we are having one of my good friends' twins as the flower girls at our ceremony(they're going to be 5), as well as my little sisters (15 and 14) as my bridesmaids(I think, is that ok that they're only teenagers??). What do I do with the little kids, there's no way their mom can get them home before the reception, and I'm not sure what kind of activites there will be for them...advice please!!
