THUMB OPPOSITION

the capacity to integrate the forefinger and thumb in pincer grip motions together. Thumb opposition starts to form around three or four months of age, even though it isn't completely reached until six months to one year old, as eye-hand coordination develops more skillfully.

THUMB OPPOSITION: "The child's thumb opposition development at this stage is a good sign that his other motor coordinations will proceed on schedule."
