Conceivably have you previously suffered through a runny nose? Conceivably did you heal from it? Naturally you did! You won't treat a common cold directly, but your immune system usually establishes immunity to a specific cold virus within a few days. That is called healed by your personal immunity!

Grownups have previously had a great deal of the runny nose infections. Parents have acquired immunity to the ones they have actually suffered from. So there are not as many cold infections existing for grownups to become infected with. That is why parents just acquire a few runny noses each year whereas children may get 10-12 colds per year.
