Infants have a variety of temperaments that can be observed when they are newborns. Recognizing each infants temperament is identifying the different emotional and behavioral characteristics (Broderick, 2015). The New York Longitudinal Study indicates that an infant’s temperament can affect the way a parent cares for them, such as making it more difficult to be a sensitive caregiver. The study also reflects on how a parent cares for their infant can influence the infants temperament (Broderick, 2015, p.145). An infant that has a high activity level might make their parent more frustrated and respond in a negative way.
