I am assuming that you mean that your son is on the computer during his leisure time - not when he should be doing homework! If this is the case but you would like him to be a bit more well-rounded, you can try a number of things. For instance, you can offer him music lessons. A lot of teens want to learn how to play drums or keyboard. Or, you can ask your teen if there is something else he'd like to learn or explore such as martial arts, painting, cooking classes or investing lessons. You can also start bringing home some really good library books - ask the librarian for teen favorites. You can set up a ping pong table or pool table in your basement and encourage him to invite his friends over. You can offer to play games with him - check out the ones that make people laugh. You can encourage him to get a job and offer to contribute an amount of money for each dollar he makes so that he can purchase something he really wants - a new computer, a car for his 16th birthday or an upgraded wardrobe. However, no matter what you do, you must realize that all people spend their leisure time doing whatever they want to do. Some kids are not interested in hobbies, money, sports, drama clubs, politics or anything at all other than their computer! And then again, some kids are not on the computer - they're out drinking or doing drugs. So keep in mind that the computer may not be the worst activity your son could be busy with. Also - are you modeling a good use of your own time. What do you do in your leisure hours? Are you on committees, socializing, doing exercise, learning a new skill, reading, doing something creative or otherwise demonstrating the kind of balance you are hoping to see in your son? Or are you just watching T.V. in the evenings? In sum, model the diversity you want to see. Encourage your son to explore different activities. Then, allow him to choose how he wants to spend his free time. Have a frank discussion with him describing your concerns and ask him to make reasonable suggestions to attain more balance on weekends particularly. If he's not catching on and voluntarily diversifying, you can make a rule for weekends that the computer can only be used for a certain amount of hours allow him to pick those hours. Keep in mind too, that he is a teenager and he will not be spending his life on the computer forever. He'll grow up one day and be much too busy to do what he's doing now.  Sarah Chana
