Adopting after cancer

My husband and I are starting the adoption research and plan to apply to adopt this year.

Long story short, I went through cancer treatment a few years ago, and likely can't have kids. I know we have a great relationship, a loving and safe home, and the ability to create a safe environment for a child. I know this child is in a position that they didn't ask for, and they don't owe me anything, but we have the space, time, energy, and income to take a child into our family.

Basically, what I am looking for is resources I should be looking into as far as research. We plan on taking classes to be trauma informed (or as informed as possible). But also interested in connecting with others who have been in similar situations, or who have any recommendations for this transition for us or for the child.

One of our biggest concerns has been to make sure we are doing this the most ethical way possible. We are trying to pursue some degree of open adoption (if the birth mother or birth family is open to it).

I haven't really used Reddit too much, so I'm trying to learn everything I can on here.
