Excellent post! As a parent watching the schooling begin I am convinced TV, computers, smartphones and tablets are the root of the majority of 'learning disabilities'. The amount of time kids spend consuming media is insane. The first five years of a kid's life need to be spent doing. Not watching. Doing! The human brain is designed for experiential learning at an early age - kids need to get dirty, play with other kids, fall out of trees, get bruised, eat worms etc.

We have friends whose five year old kids can do math at a 10 year old level. But they can't ride a bike or swim. Not joking. And it's getting worse - parents are convincing themselves that plugging a kid into an iPad or Netflix is good for them. Because it's easier than getting off their asses and going to the park. Or packing snacks and going for a play date. Or building a fort in the backyard. Or knitting, painting, cooking... 

We're not luddites and our kids get an hour of Netflix Sat and Sun morning. They use iPads when we're on the road. But that's about as much as they need - they have their whole adult lives to sit in front of a computer or TV if they so choose.
