It is a visual that has been passed down from generation to generation, from the time when you were a child to now as a parent: the classic photomontage hanging in the reception area of any pediatrician’s or obstetrician’s office. On display are the framed faces of children whom the physician has cared for – oftentimes spanning the patient’s entire adolescent life – capturing fragments of time, ranging from the first moment a baby enters the world to a photo of that same child graduating from high school.
