Frequent blinking in children can have a number of causes or it may be caused by a tic disorder. Tics are uncontrollable movements, and they may be transient or chronic.

You may notice that they can suppress the tic when they are focusing on it, and the tic will typically correct itself within a year. On the other hand, allergies, dry eyes and foreign bodies in the eye can cause discomfort that leads to frequent blinking. At times, stress may also lead to a child having frequent blinking. Eye blinking can also be a sign of a few medical disorders such as Tourette's syndrome and other eye abnormalities.
