I thought I'd piggyback on this post from a few days ago.
My boys are not asking about skin color yet--like why their skin is so different from Mom and Dad's, for example. Anna has said things though, like the time a couple of months ago at the breakfast table when she out-of-the-blue announced that she wanted her brothers to be "peach" like her and how she doesn't "like brown." Conversations like this ALWAYS take me by surprise and I have to admit I always worry if I'm saying the right thing. That particular day I told Anna that I LOVE Yosef and Biniam's beautiful brown skin, and that God made their skin brown just like He made her skin peach, and that He's creative and doesn't want us all the same. (She didn't buy it and maintained that she wished their skin was peach like hers.)
I just read this post over on Shelley's blog. Even though I'm not there yet with the boys, it seems like this is one of the hardest parts of navigating transracial adoption. As I've mentioned before, there's nothing strange for us about having two brown-skinned sons--we're not "color blind" by any means, it's just that it feels natural and wonderful--but when it comes to talking about it with small children, it's tricky.
One of the keys I think is to not be alarmed by the things kids say. When my nearly-four-year-old daughter says she likes peach over brown, she's not talking race, she's either simply talking color preference, or what she's really saying is that she loves her brothers and wishes they all looked the same. It provides a big opportunity to affirm God's plan and how He made all of us special. I know the questions will get harder as the kids grow, but for now I try to be open and comfortable talking race with my toddlers.
