A. it is in diagnosis of allergic cough cold . here the child will have regular cough and cold which is usually not associated with fever . it increases and decreases but does not get cured completely. dr will give anti allergic medicine usually motelukast / levocetirizine. if its still not improving the next linef of treatment will be inhaler therapy with mdi / nebulizer. allergy can be environmental (temperaturef variation -hot to cold weather/ cold water intake / dust / smoke / pollens) , food , chocolate / packet preservatives food and sweet foodf also. body cannot sustain such allergic changes leading to cough cold usually at evening /night and morning.
