A. Sucking: The sucking reflex is present at birth and allows the infant to feed effectively. It is a primitive reflex critical for survival and typically disappears around 4 months of age as voluntary feeding develops. B. Blinking: The blinking reflex is a protective response to bright light or sudden stimuli. It is present at birth and helps protect the infant’s eyes from injury or excessive light exposure. C. Gagging: The gag reflex is present at birth to prevent aspiration. It triggers a protective response when the back of the throat is stimulated, helping maintain airway safety during feeding. D. Pincer grasping: The pincer grasp develops around 8 to 9 months of age. It involves coordinated thumb and forefinger movement and is not present in full-term newborns. E. Sneezing: Sneezing is a protective reflex present at birth that helps clear the nasal passages. It assists the infant in maintaining clear airways and effective breathing immediately after birth.
