An Aeroflot Airbus commander let his teenage children do exactly the same thing, resulting in a crash, about 15 years ago I think.
The Aeroflot Captain allowed his 16yo son to "play" with the controls, while a rated FO sat in the right hand seat. He didn't leave the cockpit to go to sleep in business for 40 minutes with the FO! (NB: I'm not saying the Aeroflot incident wasn't
also insane.)
