Fortunately the coach wasn't moving. He was sent to the Head, and had to sit out of lunch time play. I have child locks on in my car. Children arn't allowed to sit next to Emergency exits on planes. This doesn't seem right to me that a 7 year old should be allowed to sit next to an emergency exit on a coach. I feel like I should say something to the school. It happened during a school trip. Any advice really appreciated.
