To let their children playing with gadgets.

Yes, it is good to expose kids with technology but at the same time you are actually limit children ability to interact with nature for example.

Gadgets use for education purpose is okay. But as a parent, there are limits on it. Let them use ipads or computers to learn and to enhance their knowledge with your guidance.

Like me for example, I have started to use my ipad to taught my 6months old baby on ABCs, 123s and colors. Only for about half an hour per day.
