I spent many years going through IF treatments and then moved to adoption. I now have 3 children via dpmestic infant adoption ( 3 1/2, 22 months and 11 months).
A great place to start is at your local Resolve chapter ( www.resolve.org). DH and I went to a conference they sponsored on adoption and infertility and attended several great sessions. we also got the book Adoption For Dummies ( a great resource for adoption laws in the various states as well as international adoption.)
We ended up working with an independent social worker who does homestudies and then acted as our loca agent. She reccommended several agencies and attorneys. The key for us was to work with organizations out of our home state ( Mass) as they amount of people making adoption plans is low.
We ended up working with Demastus Law Office in Oklahome ( www.dloadoption.com) one of the 9 adoption freindly state in the US ( see adoption for dummies).
