I think it has to do more with the child's maturity and interest level. My boys are 4 and 7 and they have both shot .22 rifles so far. They are both "interested", but at this point its only because I am. As they grow older we'll see if they maintain that interest, and if they do we'll certainly continue to shoot together. And at this age they're basically just pulling a supervised trigger-- it's not like they have their own rifles that they keep in their rooms and go plinking in the woods alone.
As with any endeavor where there is some amount of risk I make sure they know and practice the safety rules. In fact they both must recite the rules each time we go shooting.

Well, if you think your kids are mature for their age as well, then what worked for you would probably work for them.How early did you or will you teach your kids to shoot? Do you have a set age in mind or just when you feel they can understand and respect a gun? I shot my first bb gun around 4 first .22 rifle around 6 but i feel i was "mature" for my age.
