Questions GWINNETT COUNTY

Hello everyone I am new to this and I have a million questions. My husband and I are in Gwinnett County, Georgia and we are ready to start the adoption process. We are going through DFACS. We have been to orientation and we take our IMPACT training at the end of the month. We are only looking to adopt and we are looking for a child under 3. Which we have been told will be impossible. I am just wondering where we go from here? Has anyone had any experience in Gwinnett? I have read good and bad things about them so I am a little confused. At the orientation we signed up with an outside agency Georgia Mentor that handles adoptions for Gwinnett, has anyone worked with them? I am just wondering what to expect.
