We're just debating whether we need to continue to employ the lovely student who picks our son up from school twice a week next year when our son goes to secondary school. If we don't, our son is likely two or three times a week to be at home on his own for up to an hour an a half after school until my husband or I get home. He says he is happy with this and is a sensible boy, but I'm not sure quite what's reasonable at this stage and am concerned that so far he really hasn't been on his own at home for more than a brief period while we go to a local shop. We live in a pleasant area of inner London, and there will usually (but of course not invariably) be friendly neighbours at home if he should need someone. What have others found to be OK at this stage?
