I'd spend a lot of it sleeping and watching tv and online shopping. Then I'd book a trip to go visit an out of state friend for 2 nights that I haven't seen in a while.

This happened to me and I painted 3 rooms, took a million things to the donation center, and watched a bunch of movies. I accomplished more than I have in years. I recommend starting with a list of movies you want to see so you don’t waste two hours a night scrolling through a Netflix queue without actually watching something. I also used the bathroom without closing the door as PP noted. And ate cheese and crackers for dinner. It’s the little things that will be the most pleasurable.

Sleep, declutter (focus on DS's toys and clothes), binge watch shows/movies, get dressed without making sure the bed/bath doors are locked/closed, eat whatever you want (no sharing required), invite some friends over for at least one evening, and do at least one thing that you really want to do that you couldn't easily do with your son around. Plan out at least two days so that you get done everything that you want/need to get done.

I'd line up a bunch of meals out with friends. Either dinner or lunch. Especially since I could take a nice long lunch without needing to worry about getting everything done before I left the office, because I could work late if needed (no kid pick up!).

Then plan one weekend day to get one project done, like decluttering and organizing. One weekend day to just lounge and do something for YOU.

But I would definitely prioritize YOUR fun stuff/relaxing over house hold chores.
