There's an interesting, somewhat frightening article in the NY Post concerning a parent who allowed her child early access to electronics. http://nypost.com/2016/08/27/its-digital-heroin-how-screens-turn-kids-into-psychotic-junkies/ It describes a child spiraling into what can only be described as addiction - with all that goes along with it. I felt for the parent because she bought into much of the nonsense that was being spouted, not so long ago, about how great it is for kids developmentally to have early access to electronic devices. Her child went from a healthy kid who liked playing baseball to something from a Stephen King novel.
These devices are rewiring not only children's brains, but ours as well. The pleasure center of our brains light up when we turn on our electronic activity of choice. For the child in the article, it was Minecraft; for you it might be Facebook or Instagram. Sex and cocaine give the same rush.
Dr. Kadaras, the author of the article writes, 'Many parents intuitively understand that ubiquitous glowing screens are having a negative effect on kids. We see the aggressive temper tantrums when the devices are taken away and the wandering attention spans when children are not perpetually stimulated by their hyper-arousing devices. Worse, we see children that become bored, apathetic, uninteresting and uninterested when not plugged in.'
It also appears that the people who make and sell these devices don't follow their own advice when it concerns their own children. Their children's schools ban electronic devices. My children went to and go to public Montessori schools. These devices were and have always been banned, as they should be in all schools.
