my first son was born in Japan, when we were living there. he was the only blue eyed baby, amoungst the black haired, black eyed babies. my Japanese friends thought his blue eyes were gorgeous but I told them that all Caucasian babies are born blue eyed but the color will change to the permanent color within a month or so. my friend said that she felt sure his eyes would stay blue, so I bet her 10,000 yen (about 100$) that his eyes would change in 6 weeks. I lost the bet. His eyes are still blue, 22 years later.
