I don't mean to revive an old threat if it is unusable. However, in my plight to have my son as well trained as possible, I recognize that others may feel the same. One more thing that I will be including in this regimen are bedtime stories. He won't go to sleep without them anyway, so I may as well include firearms safety into that mix. I just bought 3 books for him; My First Rifle, My First BB Gun, and My First Bow. Hopefully, the repetition from books and his Papa's endless droning about safety, will ingrain it into his psyche. I will include the link for all who can make use of it. To all, good training!
