Well, given that I, the mother, have dark eyes and my husband is the one with the light eyes, having a child with even lighter eyes doesn't suggest anything out of the ordinary.

If we both had light eyes and the child had dark eyes that would be a different matter.

I guess if my uncle didn't own a milk distributorship, and my oldest does look a lot like him, it would be a different matter for me too. :)

Unless two of your grandparents had gray eyes, and two of them had green eyes.

Then it's entirely possible to inherit a recessive for pigment in back of the iris (gray) and a recessive for pigment in front of the iris (green) and end up with a child with brown eyes.
