So, this is an in-family potential adoption...
I think the first thing I would do, if approached with this...is assist in any way I could to help her/him find ways to raise this child themselves..
If after researching, they still feel adoption is the right choice for them...I would need to make sure we were all on the same page. In family situations can be touchy if people don't realize their roles. Relationships can be extremely strained.
I would probably recomend they check out other couples as well, so that they do not feel they HAVE to place with you....that way they can make an informed decision..
If at the end of all of this, they still want you...ride it out. Be supportive, but be prepared that they may decide to parent.
Good luck
