Education is the key, I have firearms hidden around my house that are loaded and ready for when stuff hits the fan. Although they are mostly out if reach, my children know where they are and are taught that they are off limits unless they ask and are supervised. And if curiosity ever gets to them they know all they have to do is ask to handle one or go shoot it and it's a done deal. I don't shelter my kids they know exactly what a firearm is capable of doing and the consequences. Now when their friends are over I do take extra precautions but honestly that's not that often. So again I say Education, Education, Education is the key, and they are never too young.
