Our 2 year old granddaughter has yet to see a TV or iPad or other pixeled monitor. Well, there was the one time I unwittingly let her see something, nearly giving her mother a stroke. They are adamant that she not have any of those things until a certain age, not only for manual dexterity but for vision as well.
She has pails of chalk, crayons, markers, etc.and an easel. Worked for generations, clearly still does.
That worked for us. No video games at all. No phones in the kids rooms (pre cell ubiquity). One family TV in the living room. One shared family computer in the living room until they went to college. They grew up playing sports, exploring the outdoors, riding horses, appreciating the wonders of nature, caring about animals. We all climbed Mt. Lassen a couple times and Mt. Washburn in Yellowstone together.
In 2018, oaur oldest daughter is hiking 200 miles of the John Muir Trail this summer including Mt. Whitney. Our middle daughter is hiking all over the Rockies with her dog. Our son just went camping at Big Sur and runs local hills with his buddies.
Keeping all that garbage away from kids does wonders.
In fact, when our son turned 18, we let him buy an XBox with his own money. He sold it about six months later because it was way too boring.
