Cling reflex. Hands of a newborn baby instinctively cling to a paediatrician's thumbs during a reflex test. This grip response occurs automatically for about the first four months of life, when any object placed in the infant's palm will be firmly grasped. The cling response is normally strong enough to stop the baby from falling if it is held up. This baby is between two and three days old.
