Snoop on your children. You're allowed to do that. Follow the trail of cyber breadcrumbs. Look at their profiles regularly, and click on their friends' profiles.
You want to see both what your child and her friends are saying. Often, it's your child's friends who are posting pictures of them that shouldn't be online, or giving details about their lives that could make them vulnerable, she said.
Also, click on the links your child is following. You want to know what they're looking at, so you can stop them if they're going to dangerous sites. You also need to make sure your kids aren't hiding a profile.
If your kids are 13 years old or younger, they shouldn't have access to Myspace or Facebook at all, Aftab pointed out. The sites are illegal for children that age, and it's just too dangerous to let them go on. They could join club penguin, which is a part of the Walt Disney Company, the parent company of ABC News, or www.webkinz.com, which are social sites for children. Parents can block their younger kids from other sites with a good parental control program like McAfee.
