Great stories !
I still have flashbacks of my daughter (then 8) grabbing the stick in the club T67 - fortunately at a significant altitude.
But
At risk of being a miserable b####r,
for my own protection, these days I would only take up other people's under 16's of either gender in a tandem cockpit, or in a 4 seater with another responsible adult along as well (preferably a matronly type).
A sad reflection on the times we live in.
