Diagnosis: bronchitis

Yesterday Andrew went to the doctor.  He wasn't feeling awful, but the cough he had been fighting had definitely turned into a bark.  The doctor feels he probably has bronchitis.  He is now on an antibiotic, steroid, and both daytime and a separate night cough medicine.  I am very, very much hoping that we can keep this contained to only him...Thomas goes downhill very fast when he gets sick and we don't want that to happen at the holidays!
