"The median screen time per day was an hour and a half, but the range was from none to 12 hours."
I think that a parent that just stuffs a tablet into their young child's hands and then lets them use it for up to twelve hours was not ready to have kids: either emotionally or in terms of how they prioritize the various things in their lives. And in such (hopefully) extreme cases, all kinds of developmental problems would seem like the natural consequence. Kids need their parents. It is just that simple (and difficult, at times).
