Perchance have you ever before endured a cold? Conceivably did you recover from the cold? Of course you recovered! You cannot heal an acute rhinitis itself, yet your system usually develops resistance to any cold virus within several days. We call that cured by your own immune response!

Parents have actually in the past had a lot of the cold viruses. Parents have created immunity to the ones they have suffered from. Therefore there are not quite as many runny nose viruses around for parents to become infected with. That is why parents only get a few runny noses each year whereas youngsters may get a dozen colds per year.
