Another quick update - Harry is continuing to do well. He has loads of friends now and its difficult to fit in his social life around everything else
He's just passed another grading in karate. He's now a green belt (3 away from black - but quite a way to go yet). He is really progressing well in other areas, and his private tutor has commented how well he is doing in his lessons. Unfortunately, I haven't had any feedback from school, but thats another story.
