Power of Suggestion

In light of the current health scare, I've been reminding my kids to make sure they keep their hands clean AND to keep their hands away from their faces. The minute I suggested this though, my son cannot keep his hands from his face. In fact, he now has a chronic itchy face and head. What is a mother to do? I'm hoping this swine thing is really only a guinea pig that stays away from my family....thankyouverymuch! Be safe!
