My son of age 5 years cough alot. the pediatrician are of the view that it is just a cold. what can i give him to deal with the cough?

Chicken soup: OTC meds were widely prescribed decades ago but data eventually showed no benefit to any kid under 12, and there were/are lots of ER visits for accidental overdoses.Proper rest, fluids and diet are helpful and generally all you need.I find Vicks is an air pollutant more likely to trigger cough and drainage in kids than help.I never recommend it before school age.
