Grasping occurs during the first 2 to 3 months as a reflex and gradually becomes voluntary. By 5 months, infants are able to voluntarily grasp objects. Gradually, the palmar grasp (using the whole hand) is replaced by a pincer grasp (using the thumb and index finger). By 8 to 10 months of age, infants use a crude pincer grasp, and by 11 months, they have progressed to a neat pincer grasp. By 11 months, they put objects into containers and like to remove them. By age 1 year, infants try to build towers of two blocks but fail.
