Grasp reflex of a 5 month old baby

Palmar grasp reflex (sometimes simply called grasp reflex) is a primitive reflex. It appears as early as 16 weeks[1] in utero[2][3][4] and persists until five or six months of age. When an object is placed in the infant's hand and strokes their palm, the fingers will close and they will grasp it with a palmar grasp. The grip is strong but unpredictable; though it may be able to support the child's weight, they may also release their grip suddenly and without warning. The reverse motion can be induced by stroking the back or side of the hand.[5]

Significance

If it persists beyond 2-4 months, it delays or affects functions like grasping a rattle, releasing objects from hand and also hand manipulation skills.[citation needed]
