Making your iPad kid-friendly
If you have a young child (2-4yrs) using your iPad, make sure to disable the multi-touch gestures first. When enabled, if the kid uses more than three fingers inside of an app they may close the app or switch to a different screen by accident and not understand what they did. When disabled, the only way to leave an app is to use the home button, which is less frustrating and easier for a young child to understand.
To disable gestures, go to Settings > General and turn off “Multitasking Gestures”.
