A.R.
Another adoptive mom here. I adopted my daughter from Russia as well. She was 28 months when she came home and has been a delight.
I love Russia and the people and for me this was a fabulous place to adopt from. Speaking Russian will be a bonus if you choose Russia because you are required to travel two or three trips depending on how you set things up. I choose to do two trips with my second trip being a month. One parent can go home, but the alone time with no daily chores to do gives you time to focus one on one with your little one is one of the best things I did for the two of us.
If you want to learn more, frua.org is a group of parents that have or are in the process of adopting from Russia. Also yahoo has what they call "groups". There are a lot of adoption groups, domestic as well as international. Google for adoption blogs, you will find personal journey's out there... may even find mine, you never know. Do your homework and research everything, agency and homestudy agency and learn as much as you can so you can keep the surprises to a minimum.
When you adopt there are a lot of things out of your hands, it is a very emotional journey. Be patient with yourself, and try not to cry too much, because once your little one is home you will find the whole thing was worth all the frustration.
As anything else in this world, there are costs involved. Start a savings account and put in as much as you can. If you read what the costs are on an agency's site, make sure you have more than they state. There are always extras and running out of money isn't a great plan.
Good luck!!!! And have fun with your research, there is tons out there!
