Four kids, appendix 100% of the time. Fast draw, easy control over the gun in the holster, and can quickly look down and see if little hands are where they shouldn't be. Biggest issue is when kids give me a hug and knock their head off it if they forget. If you need your gun, you kid also needs you to use that gun. They will forgive the ringing ears.
When they are older don't lie to them about, I think telling your kids why you carry a gun is important. My kids know why and not to tell other people.
