Watching TV or using a computer can be addictive, even for adults. Parents must prevent their children from developing bad habits, like spending a lot of their time in front of the TV, early on. Not only should parents strictly limit their childrens' screen time, they also need to be role models. Certainly, younger children will need more guidance, while teenagers can be given more responsibility in how they spend their time.

Moreover, watching TV is a passive way to spend time with no social interaction. While this point is not so much about computers, physical exercise and playing with other children are essential activities for a healthy development. Spending a lot of time in front of computer or TV screens limit’s a child time for such activities.
