Hot activities, like social networking and location-based apps can be fun and help your child learn how to socialize. But they can also take up a lot of time, and lead to Internet addiction and leave your child vulnerable to cyber bullies. Have discussion with your child about balancing their online activities with real-life activities, and to protect their privacy and online reputation.
4. Talk to Your Child About Positive Things They Can Do Online

Whether its blogging about their extra-curricular activities, or creating an original trailer for one of their favorite movies, the Internet offers an environment where kids and teens can develop hobbies and hone some digital skills.
5. Before Giving Your Child a Digital Device, Set Standards and Ground Rules for Use
Whether you are able to control the number of minutes on a cell phone, block certain callers or limit the number and nature of apps they use, it is important that your teen understands not all digital products and activities are meant for them to use.
As your child uses their devices responsibly and matures, allow them more privileges. Rewarding good behavior is just as important as setting and enforcing restrictions.
