Perhaps have you formerly had a cold virus? Conceivably did you eliminate the virus? Certainly you got over it! You can not treat a cold directly, but your body usually establishes immunity to a certain cold virus within several weeks. That is called being cured by your very own immune system!

Parents have currently had a lot of the cold infections. Parents have actually established immunity to the colds they have had. So there are not lots of cold viruses remaining for parents to acquire. That is why parents only get infected with a few runny noses each year and children usually get a dozen colds each year.
