Where do they learn these things?

It's amazing what kids learn at such an early age. After watching his mommy and daddy on their smart phones, Nikhil now grabs our phones and begins tapping away at the touch screen as we would do.  He has no idea what's he's tapping but he taps away anyways. He also loves the phone.  He knows that sounds will emit after pressing the buttons.  Recently he even puts the phone to his ear and has imaginary conversations.

It's amazing how fast kids pick up technology.  He's fascinated with pressing buttons and turning knobs.  Do we have an engineer in the making?
