Great list. I agree with Kollaps little treats can go a long way, also for calming down kids (bribing them to be quiet and distracting them hehe).
Another thing that I think is really important and you listed Gypsy is the emergency whistle. I carry one myself in my EDC because often just being able to signal is enough to get people out of problematic situations.
