I've got a kid in my class whose parents deliberately keep him off sugar because he gets higher than a kite. I just let them deal with that and I deal with him at school. I'm proud of him--he went up a whole grade level in reading last month.
That's great! Sounds like you are a good teacher. My parents both have dedicated their lives to teaching, too. I'm thinking of entering the family business, so to speak. I want to become a bit more mature before I do so, however.
