Hi there. We use airborn from time to time. Be careful with the dosage (double check with the pediatrition). I would suggest just a few sips. We also use some herbal teas (you can find them in Whole Foods) for kids like cold remedy. Im not entirely sure about the efficacy. My son is sick less often than other children his age but thats probably attributed to the fact that he breastfed for 3 years.
