Sure. But on a school day my kid spends around 7 hours at school. And only 3 awake hours with me. And in those 3 hours we also have to fit in breakfast, dinner, chores, and getting them ready for school. So maybe 1 hour of actual time where we can do something.

There are also weekends of course. But ultimately kids spend about as much time in school as they do with a (working) parent.
