If you haven’t already, you need to set up parental controls on your child’s iPad. To do this, you need to turn on Screen Time:
Open the Settings app.
Tap Screen Time.
Click “This is My iPad” or “This is My Child’s iPad.”
If you are setting up an iPad for a child, follow the instructions for the computer.
Enter a Screen Time pass if prompted. This must be different from the iPad passcode.
When Screen Time is set up, you have several options. Under Downtime, you can schedule a daily downtime during which calls and apps of your choice will be available. If this feature is enabled, you may also want to check Communication Limits to limit communication with your contacts during downtime.
The App Limits setting allows you to set limits for viewing time per day or for specific apps. Once the daily limit is reached, your child will no longer be able to use apps and games until the timer resets at midnight. Under Always Allowed, select the apps and contacts you want to always allow. For example, if you have a young child, you may want to allow coloring apps and YouTube Kids, but turn off Messages, Safari, and FaceTime.
Privacy & Privacy Restrictions can also be enabled, giving you temporary control over privacy. This is also where you can block iTunes and App Store purchases, block online content, set age limits for apps, control games, and turn off porn.
