Children then progress to a digital pronate grasp, in which they hold the implement with their palm facing downward. The pronate grasp involves using the middle finger and thumb. Children at this stage are able to use their thumb for tactile prehension. This stage can be mastered by the age of 2–4 years old. [13]
