[|Human|] I have a 21 month old who is constantly teething and congested. Ped says hes  normal. Tonight I heard a slight wheeze when he woke up. Hes been waking overnight at least 4-5 times crying. I have a humidifier in his room on now. Does this seem to be allergy symptoms or pneumonia/bronchiolitis?
[|AI|]  Hi, If you got him checked by the PED recently, and if he did not mention pneumonia/bronchiolitis, then, this is excluded.  However, I highly suggest getting him physically examined by the PED for further evaluation.  Usually, when having common cold/viral infection, the upper airways are congested and become narrowing. This is associated with difficulty in breathing.  I advise to: - do aerosol-therapy with saline-keep his nose/airways cleared/opened-give him plenty of water/fluids to avoid deny Chat Doctor.
