You might want to try Maven a great 3rd party app. You don't say what model you have but I use it with my mini with iOS. One of it's many features in addition to waypoints, VR and Co-Pilot, it has a "Virtual Polygonal Geofence" mode where you can setup a fly zone with a polygon fence plus a maximum and minimum ceiling and floor. You can relax as your grandson develop his skills... well almost relax, then when it's your turn, you can use all the other Maven features.
