I wondered about skin tone with my baby boy, too. I am a glow-in-the-dark white euro-mutt lol (english/irish/scottish and more) And hubby is 1/2 black 1/2 hispanic. . .Jacob is ALMOST as dark ask Gabe in the winter lol. . .In the summer Gabe tans so dark you'd never know he was 1/2 hispanic. In the winter he gets so light you'd never know he wasn't a dark-ish white guy. . .And Jacob's eyes look like they might be Green or Hazel, because when he was born they were denim blue, not already brown. My daughter's eyes were steely grey at birth and they turned chocolate brown, so you never know. He's only 2 weeks old so we will see if it changes!
Sorry for the rant. . .but I remember wondering the same sorts of things. . .I still wonder how curly his hair will be. Gabe's is really really really curly and mine looks like I have a spiral perm if I don't straighten it. If Jacob had straight hair I'd wonder where he found it! Good luck with your pregnancy

Happy and healthy 9 mos to u!
