Ask HN: How do you handle tech use with your kids?

I have a 2 year old son and I wonder how I will manage once he goes to school. He will inevitably envy the cool kids already plugged at all times on cellphones. Maybe this will cause social isolation?

For now, I try to give him a mostly screen free childhood, with occasional "treats" of dinosaur documentaries on rainy days.

How do you manage?
