Beginning with cognitive skill, babies have an innate ability to not only make facial expressions of their desires but also their needs of sustenance. But how is this possible? Using the study of Infant Intersubjectivity, researchers have discovered that “the infants need for communication animates the initial ‘self-other’ awareness and reception of motives and emotions in the intersubjective messages that underlie all languages.” “Human sense” as (Donaldson 1978) called it (Infant Intersubjectivity: Research, Theory, and Clinical Applications. Colwyn Trevarthen and Kenneth J. Aitken. Article first published online: 7 OCT 2003). Just by watching infants and newborns one can easily see the way these miniature people communicate. By observing the different tones in a cry, the facial expressions changes and or the rhythmic movements used to ask for or repel contact; these are all profound forms of infant communication. When I personally think of this form of communication the term body language come to mind. We are observing and essentially talking to infants through an intrinsic form of body language and the babes self-other awareness.
Next, when thinking about the idea of self-other awareness in infants we only need to examine a few things. When you smile at a baby and they smile back, or even when you play peek-a-boo with an infant to watch their face
