The young lady is laboring under the impression that locking up ammunition separately from a firearm adds considerably to gun safety. It’s a dangerous delusion. For one thing, there’s the first gun safety rule: treat all guns as if they’re loaded. One must assume that all guns are loaded. That holds true for your kids and you. If a gun owner reckons its OK to leave a gun unattended in a house with young children because it isn’t loaded, they’re setting themselves up for tragedy. The real answer to gun safety for children is . . .
teaching them to respect the four safety rules. And guns, generally. Let them handle them. Take them to the range. Shoot a pumpkin. Show them what a gun can do. Like public speaking, gun safety improves with practice. Meanwhile, know this: leaving a gun unattended on a night stand with young kids around may be a very bad idea. Not teaching them real gun safety is worse.
