Let me guess your pretend kid is the one who gets sick all the time and has to leave tour early because you lysoled and disinfected everything they touched as a kid?
The only thing that's going to be damaging to your kid is you "protecting" him/her against people who might not like him.
When did it become so hard to take criticism? If your kid plays football they're going to take a hit and you can't block for them, if they play baseball they're going to get thrown at and you're not going to be there to help them get out of the way, if they march corps, someone might not like their show and you can't judge it. When they go to college you can't write papers for them. When they start working you can't schedule appts for them.
Nothing is a family activity. Just tell your kid what's up, what the consequences could be, and let them live their lives.
