Back again ... looks like I held onto that post a little to long and you beat me this morning.
Kitti, how about just some good ole fashion family time every other evening or whenever it works for you. A half hour to an hour put aside just to play a board or card game or something with the kids. The point is to put the focus on spending some enjoyable time with the kids and forget about the trouble for a little piece of each day. He may still spend some of his time then in his studio, but you're giving him another option where for a time he can forget about everything else in the world and enjoy being with family.
'til later,
KAW
P.S. You could even do a family bake off ... who makes the best cookies. Last week D10 & I had a grand ole time baking muffins. Got a few smiles from CAW too.
