A lot of parents are understandably concerned about keeping their kids safe online. I know I am. My oldest is only 9, but she’s already using the internet for school and for fun. So are my 8-year-old and 5-year-old, actually. I have parental controls set up on the computer, but is that enough? I’m always hearing about various ways that middle and high school kids are fooling their parents with various apps that I know nothing about.
