This is excellent. Thank you for posting this! I am so pleased to see this positive and proactive response to the abuse scandal in gymnastics.
My husband is a Boy Scout leader. So I know it can be very difficult and inconvenient to abide by safe practices all the time, especially when parents are asking you to be at an event alone with a kid or give them a ride because they cannot do it. But it is imperative to always use safe practices, and this is why:
Of course, "you" would not harm your gymnast. But what about the next coach? (Or teacher or scout leader etc.) Teach kids (and parents) safe practices by example so they can learn and be empowered.
Second, following safe practices acts to safe guard the adult from false accusations. False accusations happen and not only are they terribly damaging to the accused person (and the accuser, who is often very troubled) but of course they also cause real abuse victims to be disbelieved. So doing everything you can to protect yourself from false accusations is an important responsibility.
As far as communications, could you use a "group" text (parent's and child's number at once) or always use email and cc the parent? My oldest son just started HS and we insist he cc me on all online communication with teachers and coaches. (And expect them to do the same.) Some communication is on an app and that I simply monitor.
As far as language, can you get someone to interpret the video? Find something else (video or written) in the kid's (and parent's) native language?
