I've heard a few stories now of young children getting out of school and heading home.... just today a friends four year old tried to make a break for it.... dd starts school next sept, and it terrifies me a bit. I see the issue, unless schools are built like Fort Knox a wilful or determined child will be able to get out if they really wanted to. Just wandered how big a problem it actually is in reality, and what can schools do to stop it?
