What could be the best way to introduce the world of computers to a kid, let’s say of 6 years old, so that he learns to handle it like a toy and stops dreading it like some esoteric, arcane and recondite machine from some eldritch, enigmatic, cryptic and phantasmal world ?


6? Go play and live doing fun things.
Computers/video games/tablets/tv that all can wait.
Yeah, the last thing you need to do is push a kid to use computers. They’ll learn fast once they take an interest. And, they’ll develop other important skills in the mean time.
