I don't have children of my own but I do "babysit" hand out with various friends' and family members' children and grandchildren. All these youngsters know where loaded, unloaded, and ammo is located, and how to operate all these firearms. These youngsters we're taught very young, like around 5 how to load and shoot, training started as soon as they started walking not to touch these firearms, and the butt whipping and/or hand smacking they would get for doing so.
By age 7 these youngsters owned their own first .22 rifle, and we're learning to handle 223/556, 357/38 spl, 9mm, 7mm-08 calibers for their first deer hunt.
These youngsters are also properly educated that firearms are for self and family property protection and hunting only.
These youngsters will check to insure household and weapons in my vehicle are secure when other youngsters are coming to visit.
Long answer to your question, but Yes.
As a footnote: firearms and ammo and extra mags/speed loaders are located together.
