How is temperament defined in infants?

Temperament in infants is best defined as an infant's reaction to their environment. This concept encompasses the inherent traits that influence how infants respond to stimuli and interact with the world around them. It reflects their emotional reactivity, adaptability, and the intensity of their responses to various situations. Temperament can manifest in various ways, including an infant's mood, activity level, and responses to new experiences or changes in their surroundings.

Understanding temperament is crucial for caregivers and healthcare providers, as it informs how they approach interactions with the infant and can help in tailoring care strategies to meet individual needs. While other options mention aspects related to temperament, they don't capture the essence of how temperament is defined by an infant's intrinsic responses to their environment.
