Narrative:

On approach to landing the six year old passenger saw me extend the gear and asked what that was. I told him that raised and lowered the gear. Upon touchdown; the six year old reached up and grabbed the gear handle and a small bump in the runway allowed the gear to come unlocked. The aircraft came to rest on inboard gear doors and nose gear doors. There were no injuries and damage was minimal to aircraft.
