Pretty much the same for glider intros. After release, let them try out the controls and take back entering the circuit.
Do read the insurance policy.
The Canadian Regulation is stupid. I was allowed to handle controls of a Cessna 210 during cruise from about 5 years of age and had my own booster seat so I could actually look over the glare shield. (When not on controls I also operated gear and flaps on my dad's command at that age.) I have done so myself once I had a license of my own and can't see any harm in that during private flights as long as it's limited to safe phases of flight and the PIC monitors it and knows what he's doing.
