| Allergies can really cause this type of cough. I had a bad cough caused by the stuff dripping down the back of my throat. It actually got worse when I went to bed - more dripping. Have him checked for allergies - it could be anything - especially in a different environment - if it gets worse at night, I'd guess it is dust - you'll need to get the allergy-proof mattress and pillow covers, get rid of stuffed animals, heavy curtains, and carpet - to keep dust down in the room. Those precautions really work wonders. |
