I remember a few years back, I think it was take you kid to work day, a controller or two let their kids transmit "contact departure". Not much to do with this with this, but the FAA took very quick action to stop it. (Bad press I guess). The delema was it specifically stated that you must not allow your child to make a transmission. At the time we had two fathers who's sons were training at our facility. Both fathers were good instructors.
