Which primitive reflex typically disappears around 2-3 months of age in infants?

The grasp reflex, also known as the palmar grasp reflex, is an involuntary movement in which an infant will tightly grasp an object placed in their hand. This reflex is crucial for early development as it can indicate neurological function and is part of normal infant behavior. Typically, the grasp reflex is expected to diminish around 2 to 3 months of age, as the infant begins to develop voluntary motor control and movement.

As the infant continues to grow, they transition from reflexive grasping to more intentional reaching and grasping actions. Understanding the timeline of the grasp reflex can help in assessing normal developmental milestones in infants, and its disappearance correlates with the infant's increasing independence and motor skills.

In contrast, the Moro reflex typically persists until around 4-6 months of age; the tonic neck reflex is usually noted until about 6-7 months; and the parachute reflex appears later, generally around 8-9 months of age. Recognizing these timelines is essential for understanding infant development and the maturation of neurological functions.
