I used to suffer a lot from the son of one of the teachers and no one ever believed me. It only stopped when I snapped one day and went off in such a rage I beat him senseless.
Never had a problem again after that from him or anyone else.

With a friendly dialogue struck up, 'his' mum may mention she was talking to you (so and so's mum) to him, and with that in mind, the other kid may become more accommodating. If it escalates, you've already made contact with the other kids parent and would potentially be in a better position to ask them to have a word.
