[Albion Wilde]

This girl just found a way to get someone else to take care of her kid, because that kid will always know who the real parent is.

I repeat, the real parents are the parents who adopted the child, committed themselves to the child, raise the child and meet the child's needs. The biological mother is not the "real" parent. She was a gestational carrier, and a noble one who did the best thing for her child.

Legally and morally you are correct. But the first time the child wants to blackmail the parents, that is what will come out of his/her mouth.
