Does it depend on the school or is there some legal ruling?
We've spent time abroad where children routinely make their own way to school from the age of 6. Now back in the UK dd1 (nearly 8) is furious that she has lost that independence and is not let out the door unless the teacher sees someone collecting her. Can I suggest to the school that she is perfectly capable to walk the short distance on her own, or will they just laugh at me?
