I would recommend you to take him for a pulmonary function test. In case it is suggestive of obstructive pulmonary disease, then he needs to be started on regular therapy. You may start with Decor 200microgm twice daily. Visit a pediatrician for proper clinical examination and follow up. Hopefully this will help you. I would be happy to help you in any further questions. Take care
