It’s no small problem: When should a parent allow a teen son of daughter to have full access to a smart phone? This knotty issue is the subject of an article on the front page of the Wall Street Journal on Jan. 13-14, and while the writer devotes a lot of space and time to the subject, she doesn’t come up with any significant hard-and-fast advice to help parents out. I came away knowing about what I knew before reading the piece, and that is that a lot of parents don’t have a good handle on this question and a great many of them have given in and let their kids have smart phones. Further, that means quite a number of kids are now subjected to harassment and abuse they otherwise could have avoided as what used to be the playground bully now finds a much larger and more effective venue out of sight of adults. Having said that, let me also say that I don’t have any particularly good insight on this. But, I do have a bunch of grandchildren, and their parents seem to have a a pretty good way of dealing with this. They don’t allow the kids to use their phones during family time, at dinner, for example. And they limit their use in other ways when it seems the privilege is being abused. Of course, too, letting the kids have smart phones also gives parents some leverage they didn’t have previously.
