Hello Dr Andrew, please my 23 month old daughter has had continuous cough and catarrh for over 4 months. It comes in at different intervals. At some point, I stopped all medications because I feared she used too much antibotics. The cough goes after medication and comes backing with recurring catarrh. Am at loss as to what I should use for her. Thanks as I anticipate your response. Please help, Distressed mom.
