Question

Quizplus · Accepted Answer

Infants typically begin to display emotional expressions such as anger, sadness, joy, surprise, and fear between 2-7 months of age. While infants may show some reflexive emotional responses at birth, it takes some time for them to develop the ability to express a wider range of emotions. By 2-7 months, infants begin to develop social smiles and engage in "cooing" or babbling, which are important indicators of their emotional development.
