That's a generalization that is not backed up by actual facts, Art. There are tens of millions of households with teens with access and so few accidents in the home as to be statistical anomalies.

Meanwhile, there are also a number of anomalies where teenagers and younger were able to access guns to defend themselves. Every family needs to make an individual, carefully considered, decision for themselves. One size does not fit all.

Toddlers and actual children under 12 (I find lumping all ages under 18 as "children" as over-broad and usually, not in this case, done for emotional effect), I'd in general agree with you. Gun is holstered on your person, under your direct control (not in a purse or off-body), or secured.
