Notice possible changes in your child's behavior. For example, if he or she has become more aggressive, has less power and gets tired more quickly, has started having problems with sleep or appetite - these may be signs of stress caused by interaction with dangerous people on the Internet. An overly elevated mood or any other things which are not typical for your child’s character can also be one of the signals to be wary of.
If your child spends a lot of time online, especially at night or at untypical for him/her hours, this could be a sign that they are communicating with people who are dangerous to them. You should also pay attention if your child chooses to be online at times when you can't hear them or find out what they are doing.
Evasion and Secrecy
If your child becomes evasive when you ask what he or she is doing online, as well as hiding, changing or closing web pages, turning off the monitor when you are somewhere near - this may indicate that he or she is hiding something. It's not always a sign of dangerous communication, but in any case, it's important to create a trusting environment so that your child feels comfortable enough to talk to you about their online experiences.
If your child receives phone calls, calls unfamiliar numbers themselves, or receive emails and gifts from strangers, these can also be signs of unsafe online interactions. Talk to your child about what to do in these situations and teach them not to give out personal information to strangers. Be patient, understanding and supportive when talking to your child.
For example, you can give the following advice:
Maintaining open communication with your child is an important aspect of keeping them safe online. Your child should feel that he or she can come to you with any questions, dangers, or concerns they meet online.
Try to take steps to build a trusting relationship and discuss online safety rules, restrictions and permissions which both you and your child are comfortable with. Be prepared to listen carefully and remain supportive and not a bit judgmental about what they tell you.
