I have an 8 year old and I get nervous when she has an internet enabled device. Games for children have lots of clickable ads that take them away from the app and onto the wild and woolly web.
Here is a setting you can change (iOS) to keep your kid in the right place. It’s a setting called Guided Access and it keeps users from errantly clicking or tapping within an app and ending up someplace they’re not supposed to be, or deleting something by accident.
Go to Settings > General > Accessibility > Guided Access and turn it on. You’ll also want to turn on the Accessibility Shortcut.
Triple-click the home button in whichever app you want to turn it on for. From here, you can select any buttons that you don’t want clicked. Or you can also disable the home button while keeping the touchscreen on.
I try to share information about how to keep yourself and your kids safe online. If there’s anything you’d like to hear more about, just let me know in the comments.
