I am only in the dreaming phases of adoption. Like the poster who said she felt drawn to China, I feel drawn to Russia and Ukraine. I don't know why.
I was adopted myself, and I have no doubt that I would love an adopted child as much as I love my bio daughters. I also believe that although I was not my parents' bio child, I was meant to be their child and they were meant to be my parents. If God provides a child to our family through adoption, it will be a child that is meant to be ours, whether that child is in the US or in Ukraine. I will have to go where my child is.
There was also a poster who mentioned adoption out of birth order. This is a pretty big deal for us. DD1 is very interested in adoption, (in us adopting, I mean) but is adamant that she remain the oldest child. DD2 doesn't care whether she stays the youngest or not. I do NOT want to adopt a infant/toddler. My ideal would be siblings that are between 4 and 12 years old. We will likely wait until our girls are a bit older and we can go with the higher end of that range. We would even be willing to adopt a teen, as long as DD1 was older. There are many teens available both in the US and abroad. We may wait until our girls are old enough that we could adopt a teen. I would be tempted to do it sooner, if DD1 were not so attatched to her role as first born.
Adding additional children will really change the dynamics of our family and we all have to be in agreement that it's what we want to do and that we're ready. We also have to be sure our feelings are truly for the child to become a part of our family and not just the desire to "rescue" a child from an orphanage or the foster care system.
I have found that even perfectly healthy children (of any race) who are older are considered "hard to place," especially if they are part of a sibling group, and there is almost no cost to adopt them domestically. Overseas, you may find them with reduced fees (that sounds AWFUL - a child who's marked down for quick sale, like a steak about to expire

) but you stil have the travel and legal expenses. It's a complex decision.
