As soon as my kid was able to play video games, we basically banned him from watching tv.

His only tv was phonics and numbers, which helped significantly because when he started playing minecraft on creative, he had to sound out the items he wanted to search for.

I didn't have any science, it was intuition.

I suppose next step is to figure out which video games are best. We basically don't let them play Idle games, but I'm starting to think platformers might need to be banned too.
