BabyCenter.com has some good resources and articles to equip you with the knowledge to get your journey started. There is a lot to the adoption process and it can be overwhelming, so it's nice to have some preliminary information under your belt going into it. The above link will take you to an article to get you started, complete with downloadable worksheets filled with the adoption agency questions and much more. It's a great place to start.
We'd be remiss if we didn't include Adoption.com as one of the primary resources for the adoption process. This is one of the most comprehensive resources available to adoptive couples on the internet.
In addition to the excitement of possibilities, there is also much anxiety around the cost of adopting a child. The cost to adopt a baby can range greatly from $0 to in excess of $40,000! However, this shouldn't scare you. There are resources out there. The cost of adopting a child shouldn't be the barrier to starting your family, and there are options out there. So check out the National Adoption Foundation's website for information on adoption grants and other funding options.
I know "support groups" tends to have a negative connotation, but it doesn't need to! Actually, adoption support groups are very cool because they're one of the most powerful resources available to adoptive parents... as well as birth-parents. Adoption can be emotionally taxing. Not only is it nice to know there are others out there experiencing the same thing, but moreover, these communities share resources they find with other adoptive couples.
