I think you are all just focusing on the what if he/she got bitten part and the effects it could have on a small body ...which is well known that a ven bite on the small or elderly are a higher risk ..as far as maturity goes ,I feel a 7-9 year old child under this situation would be more willing to do as you are telling them and lack the "I'm so good just ask me attitude " that alot of teens and just older do have ..so as far as a teaching method, the younger ones are probably a better student then the 13 +
..As far as people saying its irresponsible,there are more kids left alone with potential danger that cause severe injuries if not fatal injuries when left alone in the yard with the family dog ,parents arent even thinking of that .
Any parent that is a venomous snake owner would never leave a child unattended holding an elapid .
I think its a personal choice and its what your family life is use to ,children that live outside the "norm" do what the general public might think is dangerous and a big risk ..
but to them its a daily routine and as with everything it has its risks but its a normality as well .
I have no problems with the pictures you put up Wizz and am sure that child was in capable hands .
