When does the palmar grasp reflex usually disappear?

The palmar grasp reflex is a primitive reflex observed in newborns, where an infant will automatically grasp an object placed in their palm. This reflex typically serves a functional purpose for the baby, enabling them to hold onto their caregiver and fostering attachment.

The normal timeline for the disappearance of this reflex is usually around 2 to 3 months of age. By this time, the infant begins to develop more voluntary control over their movements, transitioning from reflexive actions to more purposeful motor skills. The disappearance of the palmar grasp reflex indicates that the baby's neural pathways are maturing and they are beginning to gain better control over fine motor tasks. This development is also important as it paves the way for further milestones, such as reaching and grasping objects intentionally.

In summary, the correct answer reflects a typical developmental timeline for the palmar grasp reflex, highlighting the transition from reflexive behavior to voluntary actions in infant development.
