Our situations sound quite similar! My daughter is 16 months old. Two months ago, her birthmother gave birth to her second child and placed him with a couple who lives about three hours away from us, in another city and state. The new baby, a boy, is my daughter's bio-half-brother, as they have different birthfathers. A couple of weeks ago, we traveled to meet the little guy and his new parents, and it all went very well. My daughter was adorable with her baby brother, and we really enjoyed getting to know the new parents. Like you, we are all very committed to the kids growing up and knowing each other.
I too did not have any feelings that this baby should be "my" child when I saw him recently, but I will admit to having had some very intense and complicated feelings when Birthmom called to tell us of her plans (when she was 7 mos. pregnant). She did not ask us to adopt this baby because she figured we had enough on our plate with our daughter. While she is correct that we were in no way ready for another baby, I found myself feeling sad and angry that this baby would be living not with us, not with his birthparents, but with another family three hours away. It's hard to explain exactly why this troubled me so much. I guess it felt like we'd cultivated a nice open adoption family with just us and Birthmom, and now our open adoption family was getting expanded without us having any input or say in the matter.
No advice for you, though, since we're just getting started with this new relationship. But I too worry a little about how others will respond to my daughter talking about a brother who does not live with us. And what might further complicate things would be if we did adopt another child at some point, then she could have a sibling who lives with us, and a sibling who doesn't. But I imagine that's only confusing for other people and probably wouldn't be for her!
