Some schools don't let kids under a certain age walk alone or get on the bus alone. Where I am, kids have to be waiting for the bus with someone at least 12 or older and if under 12 cannot walk to school alone.If you don't live far enough to be picked up by bus then you must be close enough to walk. How old is your child? Why not just walk to school, leaving at a time that ensures the campus is open on arrival?
