I have 4 children, 7 grandchildren, and 2 great grandchildren. One would think that people like me would have the ultimate answer to this to question, but I'm here to tell you that we do not. I will however give an opinion. First, know the mutually agreed upon ground rules going in. Never, ever allow your children to notice a conflict regarding themselves. At the outset, during, and ending the conflict, both parents must be what they are meant to be, and that is ONE in body, mind, and spirit.
