Thanks for the feedback. I will try to redirect them into something fun when they start asking about him. Might wake him up a bit if he sees none of us want to deal with him.
My parents invited us over for dinner last night. Of course, they included him because they're trying to stay neutral. He got there a little late because of traffic. We had already eaten, and I left for home so he could spend time with them. It wasn't 5 minutes after he got there that my oldest left for home. She didn't want to visit with him. She was crushed after seeing him.
He texted me to see how she was, and I replied I didn't have time for him I was busy with our sobbing daughter. He replied...it's best for everyone, so I said...yes it is.
Since I'm going to sway the kids away from calling, I should be able to totally ignore him today. It's tricky with little children.
