As you may know, Facebook does have an age verification feature. When you create an account, you're asked for your birth date. If the date indicates you're under 13, Facebook won't create an account.

The simple way around this is for children to lie about their age. Of course, if parents are aware their child is on Facebook, then they know they lied. In fact, the survey shows that 68 percent of parents actually helped their child set up the account. This in itself is slightly disturbing.

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.
