Infants are able, from birth, to develop an ability to sense and express a wide range of emotions freely and appropriately. While, newborn infants display few emotions. They are usually asleep, quiet, and mildly distressed. The first smile, so precious to parents, does not display the emotion of love. The newborn is not yet capable of experiencing joy, love, or hate. The first smile is in response to random firing of neurons in the primitive areas of the brain and not in response to any outside stimulation (including hugs and kisses). While, a smile has the effect of building an attachment with the caretaker and is thus important in infant survival. The first cry is a defensive emotional expression, a which is considered as an instinctive signal that release maternal behavior. A mother learns to interpret her child’s cries within days. For example, a cry of pain is unmistakable and impels a caretaker to respond immediately. The cry of fear does not appear until about seven months. The expression of fear is a function of mental growth. At first physical sensations, such as sudden noises or a loss of support, are necessary. Later, the perception of heights or strangers will suffice. Finally, the dark, now filled with mental creatures, can elicit fear.
