What causes kids to eat their snot and how can you stop this??? and unfortunately i've seen kids in their late teens supporting this habit!! yuk!

Nose: Have you ever pondered why the fingers fit so perfectly up the nose? As soon as we get hand eye coordination, everything goes to the face. Perhaps that form of behavior was a protective mechanism that helped keep nostrils clean. Kids do gross things. They're curios and the younger ones still have oral tendencies. It will stop before they start middle school!
