My kids teach me all kinds of things....

I was in college, Early Childhood Development, when my daughter was little, and she became my practicum, or in truth, my guinea pig. I was able to practice all of the newest theories , and thinking, on my precious daughter. Despite some of my misguided notions, she's a great young woman. One thing that was a absolute rock solid rule was not allowing toys weapons in our home. " Guns are not toys" and this was not up for discussion, in MY home. I judged some of the parents I knew, who allowed their children to run around with swords and pistols, " If they only knew, what I knew", I would think.
And the rule was never broken.
Until I had a son.
My friends who raised boys prior to me, smiled after the birth of my son when I said, "The rule's not going to change, guns are not toys"and for the first 18 months, it wasn't an issue. No exposure to anything but positive development toys and Sesame Street. At lunch one afternoon, in his highchair, he took 3or 4 carefully placed bites fom his grilled cheese sandwich, pointed it in my direction and said
" BAM -BAM"
They didn't teach me it was genetic.
