Emmy has been reluctant to share with one of the kids at preschool. We talk to her about it, explain why it's good to share, why it's important to have friends, etc. Emmy has humored us for a few weeks but not changed her behavior.
In the car this morning I was lecturing Emmy again when she blurted "You don't know it, but (kids name here) sticks her hand down her pants to scratch her butt and then she doesn't wash her hands. It's disgusting. I will never touch anything she touches in my whole life."
Well, that little piece of information helps put things into perspective.
