I ask because someone I know is leaving their 8 year-old home alone. It began happening a few weeks ago and now I notice the child home alone more frequently (in the afternoons and/or early evenings - like around the child's bed time or at least what should be the bed time of a child that age). They leave the child for 2-3 hours at a time. I have young children as well and would NEVER consider leaving them alone at that age. However, I would certainly consider myself to be an overprotective parent, so maybe I'm not the best judge for this sort of thing. I realize that some of it might depend upon the maturity level of the child and I will say that this particular child is not what I would consider "mature" enough to be alone for extended periods of time. Your thoughts?
