I do have some insight into adoptive issues....
First, I will say that in many cases, when the parents are somehow inclined to give up their parental rights, the grandparents have really stepped in to help care for the child in the past, and it could very easily be a situation where they truly do feel that they are just as much like a parent. They might have provided and cared for this child since birth.
But, that does not make their expectations okay.
Far from it.
In fact, as the parent and wife of a son and husband, whom my inlaws thought they had rights to.... Any adoptions aside, I would have a real problem with anyone else, even blood relative, feeling that they had these kinds of rights and expectations.
Secondly, about the adoptive issues. I would go as far as to say that in all cases, the child, at age appropriate levels (not 1 or 2 years of age) know the basic truths. I would not want this to be a secret that affects family dyamics, and then the child will feel very confused, deceived and mis-trustful, along with a lot of other heavy issues when the truth does, inevitably come out. (This sounds like the kind of grandparents who will make very sure that this child knows, very well, that they are the child's biological grandparents.)
You might want to do so research about the laws in your state... Seek some legal advice, as well as some insight/counseling from a good family or adoption counselor.
I do hope it all works out for the best!
