Oh, I'm sorry! I don't blame you for being annoyed just contemplating the level of chaos you will have to wrangle when the time comes. My in-laws spent a couple of years working on my husband's late uncle's home. He had lived there for about 50 years, with his wife who had passed away some years before he did. They had no children, and a hell ton on stuff. Just terrible. Most of the bedrooms upstairs were so bad, the doors couldn't be opened all the way for all the stuff.

I hope you are able to somewhat limit the stuff she gets for the kids?
