What options does a guy with 5 active kids have?
Well. ...
I also have five active kids. Mine are a little older now (17, 15, 13, 12, 11) than they were when I first got into defensive firearms (at the time, the baby was around 3 or 4 yrs old). And the only real reason we didn't have defensive firearms before that time was because I could not figure out how to secure them from the children.
Solution was twofold:
1) I carry during the day. When I get up in the morning, I put on my holster & gun along with my clothes, and wear it all day long whether I am inside the house or out of it. I figured I might not know what the little darlings were up to in the next room, but I could know for darn sure they weren't getting into my gun when it was right there on my hip.
2) At night, I lock my bedroom door.
Yes, that involved some serious rethinking of bedtime priorities, and we installed a "real" lock on the master bedroom door -- a deadbolt intended for exterior doors. We had long since retired the baby monitor; I purchased a new one & installed it in the younger kids' bedroom so I wouldn't feel guilty about always always always shutting my own bedroom door. Their bedroom doors, too, are always closed at bedtime; ask a firefighter sometime whether that's a good idea or not & they will tell you it is.
So. The gun comes with me to bed, and is not locked away where we can't get it. I don't retire until the kids are in bed, and when I do, I lock the bedroom door behind me. There's a little safe near my bed where the gun sleeps at night; I put it in a fanny pack at bedtime & put the whole thing into that safe. If I need to leave my room in the middle of the night, I either lock the safe or put on the fanny pack over my robe before I open the bedroom door. And in the morning, I get dressed before I leave the room, or wear the robe and fanny pack until I am ready to get dressed.
Not the solution for everyone, I know. But it's the one that worked for us.
