We have a rule they must do homework and chores after school. If it’s nice out, be outside for at least 30-60min then be off screens by 6pm. Kids are age 4-11yo
I’ve seen them fall asleep with YouTube playing in their face before and the next day is hell bc they got either terrible or very little sleep.
I like to have them explore their own interests as I did when I was introduced to computers but also set boundaries and consequences for crossing them.
