Welcome, blur!
You ask an excellent and important question.
My husband and I have five sons, ranging in age from 14 to 20 (no twins). Do the math: today we worry about the grocery bills, but 14 years ago we worried about having three kids in diapers at the same time. And between then and now, we have
always worried about how to keep them safe around our firearms.
Our first chosen line of defense has been to educate the kids. Starting when they were barely old enough to parrot stuff back to us, we taught them the Eddie Eagle rules ("If you see a gun, stop! Don't touch it. Leave the area and tell an adult.") That's necessary, but hardly sufficient. Still, even that much is far more than many parents bother with.
Next defense: defusing their curiosity. As soon as they were old enough to ask, "What's that? Me hold!" -- we let them handle the
unloaded firearms, with the firearms pointed in a safe and
controlled direction, with us hovering right there to control the muzzle and prevent little fingers from getting pinched. We let them do that as often as they asked, for as long as they asked, while we discussed the safety rules. And then we added one tiny little twist to the previously-learned safety rules: "If you see a gun, stop! Don't touch it. Leave the area and tell an adult.... and if you see a gun that you really really really want to touch? Stop! Don't touch it yet. Leave the area and
ASK an adult." No reason to sneak if permission was freely available for the asking!
Final line of defense was locking the guns up when not in use. I keep a loaded handgun on my hip for self defense, and I wear it even at home for home defense. That way I don't have to worry about fast access to a firearm that's outside my immediate control.
If I were using a shotgun for home defense, I would look at the
Life Jacket products (
http://mseworldwide.com/lifejacket/modellj3.html) or others like them. I wouldn't rely on "hiding" the gun or on putting it "up high where the kids can't reach," knowing that kids
always find stuff adults have hidden, and that even a dull child is usually bright enough to use a kitchen chair as a ladder.
Hope this helps!
