There are a couple of threads about children of differing ages being left without adult supervision at the moment. Is there a consensus of opinion?
What age...
to be left at home with no adult for a very short time, say 5 mins to post a letter or similar?
to be left for a slightly longer time alone, say 15 - 20 mins while perhaps you take another dc to a club involving a short car journey?
to be left for an hour at home with no adult in the house?
to come home from school alone, let themselves in and be alone for two - three hours. During which time they'll possibly need to get themselves something to eat?
Lets assume the child is average (is there such a thing?) and not particularly mature or immature.
