I am getting married soon. My parents are paying for the wedding and do not want kids to be at the wedding and I agree. My fiances sister and brother in law will have a fit if their children are not allowed to be at the entire reception. We are not sure how to go about explaining to them that it is an adult only reception and having them understand. We will have babysitters available to watch the children. How would yu go about talking to your future sister and brother in law about this?
