The chart has been working for Habtam, and vice-versa. He told me today that he always wants to have a chart, because it helps his "brain work better." I think one of the things that helps is seeing the smiles and sad faces and being able to remember why he earned them in the first place. He's able to go back to earlier in the day and discuss his behavior and its repercussions (hurt feelings, hurt brother, wet mother, etc.).
