A nurse is discussing newborn reflexes with a group of parents. Which of the following reflexes has the appearance of mimicking the movements made when walking?

A. The step reflex, also called the walking or stepping reflex, is observed when a newborn is held upright with feet touching a flat surface. The infant will make alternating stepping movements, which mimic walking. This reflex is typically present at birth and disappears around 2 months of age as the nervous system matures. It helps demonstrate the early development of motor coordination. B. Also known as the fencing reflex, it occurs when a newborn’s head is turned to one side. The arm on the side the head is turned extends, while the opposite arm flexes, resembling a fencing posture. This reflex does not mimic walking. C. The grasp reflex is seen when an object is placed in a newborn’s palm or sole, causing the infant to grip tightly. It is a primitive reflex that disappears around 3–4 months for the palmar grasp. This reflex does not resemble walking movements. D. The rooting reflex occurs when a newborn’s cheek is stroked, prompting the infant to turn the head toward the stimulus and open the mouth, preparing for feeding. This reflex is related to feeding, not walking.
