Your 4 month old son appears to be having a viral upper respiratory tract infection. If he also has fast breathing ,and/or chest retractions ( depression or pitting in the chest region or below the chest region while breathing) then it might be pneumonia.
If the illness is still persisting or your child has difficulty in feeding , please consult your paediatrician physically.
