Pain Sensitivity in Newborns

Newborns do feel pain, even if less obvious at birth; facial areas are most sensitive, and leg/limb reactions develop within days.
The initial pain reaction is simple: withdrawal of the affected area. With time, crying and pulling away become common when pricked or injected.
Gender differences: Studies show female infants may react to pain more than males.
Pain sensitivity & later fears: Babies who react quickly to pain tend to develop fears/anxieties faster.

Are emotions inborn or learned? Psychologists differ: Watson’s theory holds three inherited emotions—fear, anger, love—though many say emotions are largely learned and initial responses are generalized.
Generalized reactions: Babies’ emotional responses at birth are broad (e.g., a burst of movement or crying), not clearly differentiated as fear, anger, or love.
Expression challenge: Different adults may interpret the same baby expression as different emotions.

Head maturity: At birth, the head makes up about one-third of the body; body grows quickly following the cephalocaudal pattern (head to toe).
Mass motor activity: Most movements in infancy are large and undirected (mass activity).
Reflexes: Many simple native responses—withdrawal, rejecting by hand, smiling, vocalizing—do not need learning.

Pain sensitivity is present and develops rapidly; it varies by body region and gender.
Emotions are generally expressed as excitement; clear emotional types emerge with age and experience.
Bodily growth is fastest in the head at birth; reflexes dominate movement and change over weeks.
