No Babies Allowed
Yes dear, you are overreacting to blame a bridesmaid for having a baby right before your wedding. You cannot entirely control when a baby is going to make its entrance into the world. As it seems that your problem is not necessarily the existence of the baby, but the fact that you now have to accomodate a mostly sleeping newborn at your Grown-Ups Only party, there’s a chance you might need to relax a bit.
