Persistent cough of that duration suggests a form of asthma or asthma like process. There are other afflictions to consider. An evaluation by a pediatric pulmonologist would be a reasonable next step.

A virtual consultation with Healthtap is available. Chronic cough has many possible causes. A chest image is recommended. Bronchospasm is common and associated with dry cough. A wet cough is more common with infection. The lack of response to usual antibiotics, warrants further evaluation. Inquire about allergy, TB testing. If congested, use a nasal saline spray to reduce post nasal drip.
