The amount of information that can be conveyed with simple facial expression is extraordinary; a smile, grimace, twitch of the eye, puckering of the lips goes a long way in letting others knows how we are feeling. Verily facial expressions are a universal form of communication. In particular, the eyes, often referred to as the “windows to the soul” are the masters of the human face.
This is especially true of infants and toddlers who have limited use of words to communicate how they are feeling about particular events and experiences. As such, teachers must be avid observers, finely tuned to the emotions of the children in their care.
