I personally don’t let my kids have any electronics with video capability, or to have cell phones. Until they are grown, they need guidance, and giving them the ability to download anything anytime any place, or speak to or text anybody without my knowledge can easily cause them to go astray. Yes, they get upset with me sometimes, but the overall results have been that they have not gone OTD.
Learning and secular studies can be very interesting, but only if kids have a chance to concentrate and absorb it. If they do not concentrate because their minds are on other things and they are distracted, then of course schoolwork will seem boring.
Of course they need entertainment, but there are plenty of opportunities for family activities that are healthy and wholesome and do not have risks associated with them.
