Thank you for your query on Healthcare Magic.
Before suggesting you I would like to know the following :
Is he getting recurrent episodes of cough
What is the frequency of his symptoms in a week, month?
Any family history of asthma?
Any history of skin, food allergy?
Any history of atopy
in the child?
This information will guide to know the exact problems of the child and to know the severity of his symptoms and to plan a suitable treatment plan.
Consult a Pediatrician
and be in regular follow up for his complaints so that the doctor can understand his problem and advise a treatment plan.
Hope I have answered your query.
