Don’t know where else to ask

I have a friend who is pregnant and talking about giving the baby up. She wasn’t trying, was actually actively preventing but partner was poking holes in condoms and she was on antibiotics. She is miserable and doesn’t want to abort so adoption is looking good. I am super interested in approaching her about adopting her kid but have no clue how to bring up the situation. We had to do ivf for our son and not sure if my body can handle another cycle. What would your suggestions be for approaching it?
