I thought such fear mongering of anxious parents was a thing of the past. ADHD is a neurological condition, not the result of watching Baby Einstein (a favorite whipping boy of this crowd). These are the same folks who are still linking autism to immunization shots.
My kids watched Baby Einstein, Wee Sing, as well as playing UpToTen.com, Reader Rabbit, Freddie Fish, and so on, sitting on my lap, all of which I highly recommend. Are they inattentive? Sure, they're boys. But it must have impacted their schooling. If it has (and I agree it has), it's been positive: my Grade 6 just graduated with the Academic Achievement award and my Grade 3 earned 88 on his after-school math keeners club, Spirit of Math.
Let's stop lumping all "screen time" in together without paying any attention to a) conetnt or b) the dynamics of the interaction. People learn using building blocks (a miracle brain-starter, according to this article) and by smearing their fingers across an iPad screen to knock down those crazy pigs. McLuhan said "the media is the message." Modern media are active, interactive, and reactive, which makes them rich in experience and brain growth. The message is not pull the plug, it's get with the program.
(Funny how the kid in the picture they used looks as from from overstimulated as you can get. Oh yeah, TV makes you an overstuffed couch potato. No, overstimulated... no overstuffed... ah, forget it.)
Rant now really off.
