my daughter is suffering from dry cough atleast one hour a day since 2months consulted many pediatricians but no use they said it's due to weather could u please help me to reduce it

A. It might be allergic cough so start giving her turmeric milk to boost immunity abd one teaspoon honey at bed time and start with steam inhalation as well and tulsi water can be given to the child abd avoid citrus fruits for a while
