what should be given to 4 years old boy for immunity?? my son is getting cough and cold in every next month.. is it safe to give antibiotics each and every time???

A. Antibiotics are the last resort that the doctors have but if your child is constantly having this problem I believe it could be due to some allergy so you should conduct an allergy test for your child to know what is the exact situation so that you can treat your child accordingly
