As you are approaching your big day you should try to spend some time with your besties. This would be an opportune time to remember why you are friends. Try to have a girls weekend that is unrelated to the wedding. If not a weekend, a day together to celebrate your friendship will do. I would suggest a mani-pedi and lunch just with the girls. Or maybe a weekend retreat to relax and enjoy themselves. They are part of your wedding team and are ready to help in anyway. It would not hurt to give them a little time off and let them have some fun.
