Trust, But Verify
"The difference between responsible monitoring and spying is the 'Gotcha' factor," says Nurit Sheinberg, Ed.D., director of research and evaluation at the Mailman Segal Institute for Early Childhood Studies at Nova Southeastern University in Fort Lauderdale, FL. If your kids don't know you'll be monitoring their use and you find something and go "Gotcha!" they'll be shocked and probably resentful, and may start hiding things from you. So once you decide how much and what kind of monitoring you'll do, let them in on it.
Your honesty has its perks: If they know you're watching, their self-monitoring instinct will likely kick in. (Of course, kids are masters at finding ways around parental control — more on that later.) One of the best things you can do: Put the computer in a central location. There's no better way to keep an eye on things than to be able to wander by and casually say, "Hey, what website is that?"
Yes, you want to trust your kids. But they're kids — relying on their word may not be enough to keep them safe. (more)
