My daughter started when she was 9. She had been in the woods with me from shortly after birth...packed her around on a pack frame. My son killed his first deer when he was 7. He is better with gun handling than most of the adults I hunt with. He too doesn't remember when he was too young to go to the woods with me, or fishing, or 3D shoots...they are my kids, they just go with me everywhere, and they learn. I know them, and am not in the least concerned being around them when they are toting weapons. However, if I were to stumble onto a father/kid in the field with the kid carrying a loaded gun, I'd be concerned. Funny, we as a whole tend to think rules are for everyone but ourselves (at least I do). Having said that, I agree, it's up to the parents.
