The Palmar Grasp Reflex is a natural reflex seen in newborns, where they instinctively grasp objects placed in their palms. This reflex typically appears at around 28 weeks of gestation and can last until about 5 to 6 months of age. It is an important developmental milestone, indicating that the baby's nervous system is functioning properly. When a baby's palm is stimulated, the fingers curl around the object tightly. This reflex is thought to be an evolutionary trait, helping infants cling to their caregivers for safety. As the baby grows and develops voluntary motor skills, the palmar grasp reflex gradually diminishes.
