We did foster to adopt, so I don't have advice much on fund raising (although I will say our decision to go this route has been a financial blessing to us - our daughters ended up being medically complex, and had we not been able to keep them on state insurance their medical bills would be a big strain on our family. Also the monthly stipend we receive helps to fill in the gap for all the work we miss taking them to appointments. And the college tuition that CT offers to children adopted through foster care will be awesome if they choose to go to college). If you have questions about what criteria you are open to (age/race/drug exposure/open or closed adoption/etc) and want to bounce some questions off of someone, please feel free to PM me. Although we have had our girls since they were released from the NICU at 3 weeks old, there are some nature vs nurture type issues that we are still overcoming and the girls will be fighting against for the rest of their lives. It isn't easy, and nobody can really prepare you for what raising a child with drug/alcohol exposure is like, but I will be happy to pass along our experiences (we are still foster parents, so we have had many kids come through our home)
There are many groups on Facebook for adoptive/pre-adoptive parents. I am sure they can point you in the direction of some great fund raising ideas. Best of luck!
If you are on Facebook, start to follow Mark R Miller, Esquire-Adoption Attorney. His fees are high from what I hear, but he seems to do a lot of work with the birth families prior to the baby being born to ensure that the adoption is in the best interest of all involved (he is in Florida and makes sure he does his due diligence in regards to birth father's rights. There are some states in the US that have horrible birth father rights - some unscrupulous agencies have even been known to fly birth mothers to these states so they can get away with avoiding the legal process of terminating fathers' rights. These are things you should become acquainted with if you do domestic infant adoption. Also be aware of if a child qualifies under ICWA - some agencies don't do a great job explaining the risk of taking one of these kids if you do not have a link to a registered tribe.
