Adoption

I would like to know more about adoption. I know in my heart it's something that is meant for my family, but I would like to know what is was like for you & your family. What was it like for you? How long of a process? How costly? Where did you adopt from? How did you find an agency? Please feel free to share as much as you'd like. 
And everyone remember this is a sensitive subject, be gentle with your words, I am just asking for personal experiences. 
Thank you, God bless.
