Croup again?

Hilton is sick, again. He has some kind of coughing thing. I was pretty sure it was croup again the other night. He has the typical symptoms, but today he is coughing uncontrolably. He will not stop coughing! And in the past, when he has had croup, he doesn't cough much during the day. I called the doctor and of course he can't see him until next week. And what is the point of that, exactly? Anyway, I am trying to keep him calm and watching tv, but he keeps playing star wars and jumping and running around. I just don't know what to do with the boy.
