I pretty much forced my kids to doing things unsupervised starting around 5. I'd have them go to the mailbox at the end of the street, around the corner just out of view, and get the mail. 1 out of 3 kids was hesitant but I sent her anyway. Then they branched out to the park a couple blocks away, by then they were asking if they could just go - they had learned to be comfortable alone in the world.
