I've noticed a lot of different threads asking how to afford adoption, so I thought I'd throw in my 2 cents.
DH and I decided to adopt BEFORE ever trying IVF, so it wasn't a very difficult decision. We were very blessed with the means to do it, but yes, it can be very expensive. There is an $11K tax CREDIT for US citizens which is an enormous help. It comes after the adoption is complete, so you have to shell it out first, but it's there.
There are a ton of grants available and lots of ways to fundraise. Also, think of it as investing in your child rather than buying that new car. If you want to do it, and really believe that's what you are called to do, you'll find a way.
A great resource is www.myadoptionlinks.com. You'll be able to research a lot of countries and it should help you look into US adoptions as well.
We have been so blessed with our two kiddos, and they have brought such fullness to our family. I know for some it's very hard to give up the thought of having a biological child. Adoption is not something to take lightly, but wow, is it amazing.
DH and I wanted to see if we could have bio kids, so now we are going through IVF. For us it's just another way to have a child. I don't take it lightly and I would REALLY REALLY like to be pregnant, but God has certainly blessed us already.
It's a scary journey, but you'll find a way. Let me know if you have any questions. I'm actually about to teach a seminar on adoption, so I've done a lot of research!
