KNOW THE DIFFERENCE BETWEEN RISK AND HARM. It might seem like just a semantic distinction, but recognizing the difference between risk and harm is important. Livingston contends that while the risk is real when it comes to being exposed to inappropriate material online, the probability of harm is low. ???The risk remains but the parents??? task is not to eliminate risk but do everything they can to make sure the low probability harm doesn???t happen to their child,??? she says. ???Children have to encounter risks because it???s how they live and learn. It???s how they go out into the world and become resilient.
