My wife and I have found similar results as an experiment with three of our children (yes, experiment) progressively allowing more screen time per child at a younger age. We have found that attention span alone is inversely proportional to the amount of screen time allowed. We now limit to just 1/2 hour per day per child in a family of iphones, ipads, itv, laptops, kindle, etc. As a result, our oldest who collectively has as much screen time as our youngest is into reading/writing, drawing and someday soon I intend to get her writing some code. Of course, your millage may very, and I'm not quick to judge others when it comes to parenting. Not an easy task.
