I thought that this was an article about politics, based on the title. Pleasantly surprised to learn that they meant it literally.
I have a very young son, and it has been my plan to try to keep him away from screens, but I have to confess that I don't really know how. We run so much of our house through our phones (lights, stereo, shopping, etc) that it's inevitable that I pull out my phone pretty often while I'm with him. I'm sure I'm inadvertently desensitizing him. I could do a better job, but it feels sort of inevitable that kids are going to be screen exposed way sooner than we'd all like.
