How to get a tidy room

A couple of ideas for parents who go out to work (or want to escape). Although, in the first one I’m not quite sure how the little cherubs would manage to email without WiFi. Yes, i know they might have data on their phones but then if that’s the case they might not be overly bothered about WiFi….

In this one I like the use  of the crackers to prevent smart kids reusing the same pic. pic-2
