yes I had pure blue eyes like an ice blue now they are more of a greenish blue with some yellow mixed in. that's because the bluer the eyes the less pigmented they are, dark blue is the least pigmented and so kids often don't have their full pigment yet, so their eyes are likely to be bluer or lighter and their hair is probably lighter too.
I guess not.. I never paid attention to their color when I was very young, now I have green eyes and probably my eyes were green also before.
But my hair color did change.. I had red hair when I was a kid but now they're brown.. at least that's what other people from my family say to me, maybe they're right as now when I grow a goatee it gets very obvious shades of red.
I was born with dark *yet bright* green eyes and they turned like a pastel light green and when I turned 12 they changed to dark brown in over a week, it was really weird..I got sad, then I didn't mind my dark eyes, I got used to them:]
It's pretty common for babies and young children to have blue eyes which darken or lighten or even completely change color as they get older. They change to the "true" color which is what you have now.
My eyes were also blue when I was younger. Now they're blue/gray
