I taught my kids gun safety and how to properly handle and safety check firearms at a very early age. The biggest thing I did was take the mystery out of it by telling my kids that they could see/handle any of my guns anytime they wanted, just ask me first and I will never tell you no. Took all of the mystery away and never had an issue. Take the mystery and taboo (you cant touch this) out of things and you'll find kids quickly become disinterested.
