Keep the computer in a communal place so you can keep tabs on its use. Make exploring the Internet a family activity that involves making discoveries and working on projects together.
Set limits for your child and be consistent in enforcing them. Try using a timer to signal that the child's time is up or use verbal countdowns, such as "10 minutes left" and "five minutes left."
Download software--such as Cybersitter, KidsWatch, and iNet Protector--that will control your kids' Internet usage for you. The programs limit time online, restrict access to inappropriate websites and provide reports of usage.
Provide enjoyable alternatives to the Internet. Get your child involved in activities that will stimulate his development, such as art classes, team sports, dance classes, cooking lessons, etc.
Connect your child's online interests to real life. For instance, if she enjoys an espionage video game, buy her a book on famous spies or take her to a museum of criminology.
Set specific requirements for time online. Link the completion of homework or chores to Internet use, or barter time spent outside for time spent online.
Limit Internet usage to the weekends only, except when using the Internet as a research tool for homework.
