Hello
Believe it or not, try a spoonful of honey. This is about the only thing I've found that works when my daughter is sick.
Also, get a humidifier going in his room, and make sure he's drinking plenty of fluids.
If it gets real bad, take him into a closed bathroom with steam full force from the shower.
