It isn’t obvious to me why you think iPhones and iPads have retarded some of the cohort? Can you expand on the causality of it and what ages are you referring to ?

I can’t tell you why. I just see a correlation. Age group up to nine.

I’ll add: it’s especially notable in ability to focus and communicate. This is my take knowing and coaching many of these kids in youth sports.
