Hi, Welcome to Hcm, Recurrent episodes of cough, cold can be suggestive of reactive airway disease. Especially if he is again and again getting exposed to dust, smoke or some allergens which might be triggering his problems. You need to identify those and try to avoid those exposures in him. Few measures like dusting mattresses and drying in sunlight twice in a week. Wet mopping of floors. Avoid smoke inside home. If such measures doesn t help, then it might be necessary to start him on preventer medications. For that a confirmation of the diagnosis needs to be done by a pediatrician . hope these measures helps. Happy to clarify further doubts. Take care.
