Hello @ictaylor
If your son's gmail account has been added to the Google Home, he will have permission to unpause himself through the app. If he hasn't been added that way, he may simply be changing the MAC address on his device(s) to get around the restriction. In my experience, when children get old enough to work around these simple tools, the solutions are either to continue trying to use technology to enforce the rules (e.g., by using Microsoft or Apple features to enforce policies at the operating system level), or to use a non-technological approach (e.g., take the devices away).
