I don't know, they both have brown and so do I, and my brothers. My mom and dad each have multiple brothers with blue eyes though, and each have multiple sisters that are ALL brown-eyed.
I married a brown-eyed man, so both my kids have brown eyes (actually, they are so dark at birth, they look black, and gradually fade to dark brown as they grow...........DS1 is now 10 with eyes about his dad's color which are darker brown than mine, and DS2 is 3 years old, and his eyes are still very dark.
Queen of the stories: I have one about eye color. My dh was playing with my son..........kind of flipping him over and growling, and "chinning" him one day when he came home for lunch. My son was about 18 months old or so. Well, he dropped him. Right on the top of his head, about 2 or 3 feet off the floor. We were in an apartment with a thin carpet and pad over a concrete slab. My son immediately began vomiting, and I panicked. I called the dr.'s office right away, and they asked me to see if his pupils were equal and normal-sized...........I could not see his pupils! I told the nurse, and she panicked.........and I said no, his eyes are so dark, I can't see which is iris and which is pupil...........we had to take him outside in the sun to see! He was fine, btw, and it was just before naptime, and they said not to let him nap, so I had a very cranky toddler until about 5, when I just could not keep him awake any longer. Then I had to wake him every 2 hours through the night.
, but my son got the green!
