Have any of you bought books on this subject? I was just looking through Amazon and a couple I saw were "Black, White, Just Right" which is for the kids and "I'm Chocolate, You're Vanilla: Raising Healthy Black and Biracial Children in a Race-Conscious World" which is for the parents. Any titles you would recommend? Are they helpful/necessary? When do kids notice this stuff anyways? DD sees a guy with glasses on TV and says "Daddy" or an old guy and says "Grandpa" so she hasn't noticed skin color yet!
