It is a wisdom issue and every family will end up at a little different place on the continuum. I am going to suggest some websites where you can get more information. The National Center for Missing and Exploited Children have an extensive section on their website about internet safety. There is information about basic internet safety for a variety of ages. There is a section for parents, children and related issues such as chatrooms and text messages.

These are some tools that may be beneficial. It's hard to read about some of the things that can happen and I want to impress: God is our protector. As we are faithful to learn and teach our children how to stay safe on technology, ultimately, we have to depend on God to keep ourselves and our children safe in all areas of life. This is not an area that needs to overtake us in fear as that only paralyzes us as parents and people. Use this information but trust God for his protection in the process.
