I don't know. When I was a little kid, I rode horses for at least a year or more before it dawned on anyone that I was extremely allergic to them.

Maybe it takes a little while for the allergy to build?

My kids all love chocolate, but have developed a mild allergic reaction that causes them to breakout in hives if they have too much over a short period of time.

They didn't start out that way.
