First of all, on the age difference issue... my kids are over 5.5 years apart. I never in a million years would have planned that, but God knew better and it has been perfect. They get along so well and while my daughter is still young, they don't fight over toys. I have 3 siblings myself and the one I'm closest to is my little brother who is 9.5 years younger than me. So, closeness in age really has nothing to do with whether they'll get along. More about personalities.
My son (bio child) is CC and my daughter (adopted) is AA/CC. I get what everyone here is saying, really I do. But we are done building our family and so yes, my daughter will be the only one of her race. But I guess I'm okay with that for a few reasons. First, we do share part of her ethnicity; and the same ethnicity as her birthmom. Had my daughter not been placed for adoption, she would have (most likely) grown up the only AA/CC in her bio family. Second, our lives are diverse. We have friends from all races, dh is in the military. And we will always make it a priority to live in diverse areas, seek out diverse schools and maintain friendships with our AA friends. I could be all wrong about this, and maybe my daughter will write a book about how growing up the only adopted AA/CC person in her family ruined her life. But I don't think so. I think the harm can come when you are not aware that it COULD be an issue.
If you can adopt another AA child, then yes, that would be ideal. But if you cannot, then that's okay too. You are aware and Caleb will be fine! Goodness, can I talk or what??
