I have had many discussion with people about what an good age to start showing your children gun safety. I have had some ignorant people that have said not to show your kids, but keep them locked away.
Me personally I started teaching my nephews when they were real small. Then when I had my daughter the lessons started about the time she could walk. Now she is three and she handles weapons more safely than most the idiots at the gun range.
When you hide something from kids they become curious about it and will find a way to get them.(You guys know what it was like with Dads playboy's) If they know about guns then the curiousity just is not there. A gun to an educated child is a tool that serves a purpose and they do not want to try to figure them out for themselves. Where I live you are raised with guns leaning next to about everydoor in the house, and you know what they are for so you do not playy with them.
My three year daughter knows how to clear my AR15, XD, and ou revolvers. When she is wants to handle one she askes and I make her go through all the safety measures. I had her at the gun store one day and I was looking at a rifle. I was checking the chamber when a guy next to me said why do that you know it is not loaded. My three year old daughter chimes in "Mister all guns are loaded untill you make sure they are not." There was probably 5 guys standing around that started laughing at the guy and complimented me on having such a smart kid. The guys face turned red and walked out of the store.
So how old where your kids when started traing them?
