The App Store Review Guidelines require some apps to include a parental gate. There is no set way to do this, but we’ve compiled some examples below to provide inspiration for creating gates in your apps for kids. A good strategy is to randomize the combination of questions and answers each time the gate is presented to prevent kids from memorizing the responses.

As you plan and develop your app, read the App Store Review Guidelines and make sure your app meets the requirements of all applicable laws including children's privacy statues. For more information on how to prepare and submit your app to the App Store, read the iTunes Connect Developer Guide.
