The internet can be a great place for children to learn and play games. However, many parents worry about their children discovering content that is not "kid-friendly."
How to set "Safety Mode" on YouTube:
If you want to filter what your children can find on YouTube, you can enable "Safety Mode." To do this, scroll to the bottom of any page on YouTube and go "Safety" and click "On." This will block content that has been determined to not fit community standards. Some searches may return zero results and other searches will return filtered results. All comments are hidden by default. The safety mode filter also applies to related videos.
Other options for parental controls include:
iPad - you can enable restrictions by going to Settings->General->Enable Restrictions. This will allow you to remove access to certain apps, YouTube, Safari, etc.
Computer settings - You can set parental controls on your PC. Here's a how-to guide.
