I will say that last week he asked me if "we" still have the old space heater because he's afraid the floor of the laundry room is too cold for S8 to sleep comfortably. I said I didn't think "we" did and he said he didn't think so.
At least he's concerned about their well-being when they're present.
Kids opted to not buy him any video games for Christmas. They got things they thought he would enjoy IRL. They were very thoughtful and demonstrated that they really understand him, which is nice.
