ITA with Portia - you need to determine what works for each child. I also believe it's ok to insert your own family values into decisions about screen time - while it's a wonderful tool for learning, it's not the only way to learn, and I'd be very cautious about assuming he's learning "more" via screen than he is when he's interacting with his parents or out on a walk, etc. I'm guessing there's a good likelihood that he still enjoys time with his parents
If so, maybe one way to handle weekdays that both allows him to follow his passion as well as help alleviate concerns about too much screen time would be to let him have an hour before dinner time, and after dinner time spend some one-on-one child/parent time - could be reading together, could be playing, could be anything.
Best wishes,
