My generation did not have access to the internet until we were teenagers, yet we perfectly managed to catch up. In fact, I don't think that the following generations (the so-called 'digital natives') have overall better computer skills, on the contrary.

In general, the last thing young kids need is more screen time. My 5-year-old daughter doesn't have access to any mobile devices. She enjoys drawing, handcraft, reading books, singing and playing the piano. I'm perfectly happy with that.
