The rise in teen suicide, juvenile crime and child anxiety can be traced (at least in part) to the use of smartphones. I have heard child psychiatrists acquaint giving a smartphone to a child with giving them a heroin needle. So why would a loving parent get one for their kid? The answer, of course, is peer pressure, and a contest of wills between parent and child.

The answer, must be legislation. Give parents a break and allow kids to only have “dumb phones” until eighth grade. Only if we do this as a culture, do we have a chance at saving out kids. Ohio just passed and is implementing a “no phones” in school policy. We will see how that works. If behavior and academics improve, then I see no reason to not implement a kid smart phone ban.
