Omar Wasow Internet expert Omar Wasow explains how to monitor your child's online usage if you suspect they might be accessing self-destructive sites.
Use "Control-H" while browsing the web to see a list of websites that have been accessed in the last few weeks. This can help you determine if your child is visiting any dangerous websites.
Install filtering software like Cybersitter, Cyber Patrol or Net Nanny. The software costs about $40–50 and acts as a digital chaperone, blocking any inappropriate content. These programs work by checking which sites your child visits against a list of disapproved sites, compiled by the makers of the software.
A more extreme approach is to install software that will actually record images of every website that your child visits. The software won't stop them from accessing sites, but it will let you know if you have a problem.
The most important thing to remember is to be a part of your child's online life as well as their offline life. Talk to your child about what sites they visit, who they communicate with and who's on their buddy list. No software will ever be a substitute for being an active parent.
