how can u tell if a baby has seasonal allergies or a virus?

[tffnyhzl]

my baby has a runny nose and is very congested but the mucus is clear. i went to a dr. to see if it was a cold they said it was viral but he's had it for over a month now.... could it be allergies or a virus?

where do you live?? My daughter is 2 and her and I both had a nasty cold that lasted about 3-4 weeks. After the sneezing and nasal congestion it went down into our chests. We had loose chest and nasal congestion that ran clear for about 3 weeks. Im in MI. Allergies will also cause a clear runny nose. Did she have more symptoms when it started and now its down to just a runny nose. If so then it was a virus and just has to work itself out. If not then it is definitely a allergy if she is sneezing and has clear mucus drainage from the nose. Hope this helps..
