Has your H already, or is he planning to take the kids to his "new" place? Maybe if they got a chance to see where he is going, that would give him some sort of comfort that he's not going somewhere and never coming back. Obviously, it is not a solution to their sadness, but may help a little.
Good job on the fridge! I need to go through mine..sigh. I will look up the "40 days to clean a home" list.
Oh...I was watching Wife Swap the other day, and there was one wife that wanted to frame a kid's artwork and hang it all over the house....Do your kids draw or paint? Maybe it would be cool to get them involved in framing some of their art and let them choose where they want to hang it?
