What's also important and has been posted about before, is actively engaging your family in the scenario...What happens if? Code words, for the kids to get low, stay put, or a plan of your own choosing, but involve them like a fire drill at school. They will remember if God forbid a window breaks or door is kicked in at 3:28 a.m....
Depending on your housing, apt. condo, single family, will determine a course of action...Know your house in the dark. It's a big advantage the potential BG won't have. Know your safe lines of fire utilizing exterior walls, hallways, areas away from windows, or thinner walls if in an apt. situation.
In essence, recon your house, involve your family in the direct steps needed in a crises situation. (Age matters, but if the kids are old enough to know a fire drill,)....
Scope your house in the middle of the night, identify vulnerable traps, have a back up plan...(Wife with a 12 gauge works well),..but think it through, explore the goods and bads, and in your specific home environment, you will see it.
All the best.
