Hello there!
Anisocoria refers to a difference in pupil size and 20% of normal people may have as much 1mm of difference. What your son may have is known as "simple anisocoria" and the pupil sizes in such individuals commonly change from day to day and even from hour to hour without any serious underlying cause.
There are other causes of this such as:
Horner's syndrome, third nerve palsy, adie pupil, stroke, iris damage and certain medications.
It is very normal for people to have different size of pupils.... but in saying that you should take your son to see a doctor to rule out any possible serious underlying causes...especially since he is so young :)
