Thanks for responding

We have already met with the social worker once. That was two months ago. At the time, she said that the entire home study should take two to three months. They do quite a lot of adoptions a year. She said that when they don't have a lot of waiting couples for AA babies, they pull profiles from an agency in the northern part of the state. When we met with the social worker, and when we spoke afterwards, she said that we were a great fit. She had already told us that they are always looking for families willing to adopt AA newborns.
All of that leads to us feeling confused and frustrated. I emailed a social worker who has a local office and only conducts home studies. I am going to see what she has to say about time periods. I think that if we used her, we could still adopt through our original agency. I hope to hear from her before we see our social worker because we have to pay the first half of our home study fee when she comes over.
