What causes my 10 month old baby to have a persistent cough of over 3 weeks?

A doctor has provided 1 answer

Reflex activityd: Cough is a reflex that is caused by a message from the bronchial tube to the lower brain. It might be caused by an input message to the brain (e.g. Infection) or an unnecessary executive message from an irritable brain. Strangely enough it can be caused by sugar intake or even cow's milk. This is partcularly true if he coughs in his sleep without awakening.
