I don’t think the foster mom is Mormom, and she used the term “forever family.” It seems to be a term used today by many people for adoptive families. (That is, instead of bouncing around from one foster family to the next, a child is adopted “forever,” hence the term “forever family.”)
I noticed this after the Google© search.
