Not a matter of age. It depends on maturity. I don't know your boys, so, I can't give an answer. My son could be left alone for periods of time starting at 8. And longer and longer periods as he became older and more mature and reliable. He is 13 and can pretty much stay on his own all day..probably longer, but, not going to let him stay longer than a workday + a little grocery shopping added on. No need in longer than that. But, he was coached on rules, senarios and more before I left him. He also had a binder that I wrote down any info he could possibly ever hope to need in it. plus left notes and he could call me or my mom as needed.
