At 3 months voluntary reaching gradually improves in accuracy. It does not require visual guidance of arms and hands, but rather a sense of movement and location.
By 5 months reaching is reduced as the object can be moved within reach.
At 9 months an infant can redirect reaching to obtain a moving object that changes direction.
6-12 months the infant can use a pincer grasp, increasing their ability to manipulate objects.
