But preteens may interpret your concern as an attack on their privacy. Here are a few neutral ways to approach the subject. Acknowledge your child's perception, but let her know how much you care about her. There's a lot of pressure on preteens to grow up before they're ready. Don't be afraid to let kids know that they don't have to.
People can lie about their age, whether they're a boy or a girl, or all sorts of other things.
Children need to be reminded that they really have no idea who they're chatting with online. It's important for kids to be clear about your expectations for their behavior on the Internet. Not giving out any personal information, not purchasing anything, not arranging to meet someone you get to know online, and using an online pseudonym are four of the most common rules imposed by parents. This needs to be an ongoing, evolving discussion with kids. How much privacy you allow your child will depend on your own values, your child's age, and your sense of his or her judgement.
