i had my little one helping me last year at 5 but after stumbling across some very disturbing studies concerning lead and the impact it has on children in the developmental stage, i abruptly put a stop to the practice. My initial concern was brought on by the fact that i cast but after reading how much more dangerous spent primer residual dust was, i cleaned the house from top to bottom, pack up all of my reloading stuff and set up shop in the garage. I'll let him start back after i'm convinced that something i introduced him to is not causing long lasting mental disabilities. I am in no way telling anyone they shouldn't let small children around the bench. I've heard both sides, about how their fathers' had them reloading young and they've turned out fine. But for me, the risk is not worth the benefit. YMMV.
