I like that though, just chilling for a day or two, do what you feel like and not what feels important. If your life doesn't give you the opportunity to do that I'd suggest try to get more flexibility, you don't need to be super attentive and productive every day. ADHD isn't a disease, it just means you are badly adapted for modern office work and bureaucracy, and having vacations where you can go back to your simple carefree self is very valuable.
Edit: For example, when I was a kid I spent most of my time at home playing with toys during weekends. I don't see why that would be a bad life for a kid. When they get older to 8-10 they can get around on their own so no need to baby sit them any longer, at least if you live in an European city.
As for parenthood its not just about bringing your kids places. They want to play, they need to eat, they need diaper changes. Kids are a ton of work I love every minute of it, but man is it difficult.
“Playtime” is a tool used to prepare the child for the next lesson.
Even non-ADHD people should be doing that. I rarely take medication on the weekends and if I do, it is strictly only one day.
The other day I allow my brain to do whatever it wants; play video games, lay in bed, work, it's free to tell me what to do. It's relaxing.
