Parents' knowledge of their children's Internet use is rapidly decreasing. Children are withholding more and more from their parents, including how much information they are sharing over the Internet. Parent-child self-disclosure about this topic needs to be increased if interventions are to help keep children safer online. Notably, there are many parents who have even admitted to allowing their children to lie about their ages on social media sites in order to gain access to them. Parents, thus, are encouraged to remain open to discussing such things with their children, to use better judgment themselves when making decisions about their children's Internet usage, and to provide them with education about how privacy on the Internet is a risky notion.
