#AskTheExpert My daughter is 4.5 years old and weighs only 14.5 KG. She has been getting cough and cold every 15 days whole of this year. Local paedetrician says she is alergic to changing weather and dust. We keep her inside house most of time and give all kind of care we can but she remains ill. We have been giving her Allegra syrup and nebulization but nothing is working. Please suggest.
