My biggest concern right now is how to talk to S4 about this. I am more concerned than WAW right now; she thinks he is too young to understand but I think he will get it more than she thinks. She also is coming from a family that parents divorced when she was 7, and she thinks of it as a positive thing. I'll be researching more on how to talk to my son, but any advice out there is appreciated.
Coach had a great way he handled this, although I believe his kids were older than your S. He made his W (Greek) do all the talking. He was present. When his W was finished, Coach looked at his children and asked them if they had any questions of him. If I have to have this talk, that's how I'm planning on handling it. Goes along with the don't resist but don't assist mentality.
