Setting restrictions on iOS can be an easy way to protect your child and your credit card on Apple devices.
This will take about 20 seconds
Enabling Restrictions on iOS is fast. From the home screen:
Open the Settings app
Tap on General
Scroll down and select Restrictions
Tap Enable Restrictions and set a passcode.
The Restrictions passcode should not be shared with your child (duh), it’s just for you — this is different than your phone’s lock screen passcode. And that’s it. Told you it was easy.
An important restriction in this section to check is websites. You can choose to give your child access to: all websites, websites with limited adult content or specific websites. You can even add specific websites that you never want them to access.
