We used an agency in Kansas and were very happy we chose them. Very helpful, dealing with the same contact throughout, and all the fees are listed up front, which means no surprises. We did semi-open, letters and pictures, occasional phone calls, but no visits at this time (but keep an open mind!). FindingMercy explained things so well in her post, I won't repeat. But just also know that there are no guarantees in newborn adoptions. We still had 4 weeks in the NICU and another week away from home until paperwork cleared. And having 3 bios may turn a few E-moms away, but there are those E-moms who are looking for brothers and sisters for their LO. Good luck!
Loving life with our very energetic 2 year old b/g twins!
