With so many children under 13 on Facebook, does this change my stance? No, not really. There are a lot of reasons to keep your child off Facebook.
Obviously, there's the growing problem of online bullying. Even teenagers and college students have a hard time dealing with this. Do you really want to risk your pre-teen's emotional wellbeing?
Then, of course, there's the opposite problem. Some people might want to get too friendly with your child. Can your child distinguish between a new friend and an online predator?
Compounding the problem, children already like to share about themselves. Facebook encourages sharing of everything, including personal information they shouldn't give out. Unchecked, they can put themselves in serious jeopardy.
