Accidentally exiting the app / Turning off Gestures
If you find that your little ones are accidentally exiting the app it might be because of Apple's multi-touch gesture system. It's a great system for adults, but can be difficult and frustrating for children.
Here's are step-by-step instructions for turning those gestures off.
1. Open "Settings"
2. Open "General"
3. Open "Multitasking & Dock"
4. Toggle "Gestures" Off
Now it won't be so easy to accidentally exit out of the app when you don't want to.
