The other thing your are not that well adapted for is parenthood (lots of getting shit together and going someplace on a schedule) and that is harder to take a break from
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.
