What you guys are seeming to forget is that, in kidnapping cases, the person being kidnapped is not the only victim. Not only did this person take an infant from her biological parents, and craft this child into something entirely different than the birth parents would have done, she did something far worse. She took, from the birth parents, evey milestone that could possibly have been had with their child. The actual parents were robbed of hearing that child's first words, seeing the child's first steps, etc...
"But, the kidnapper was a good mother." Bullshit, and completely irrelevant. The kidnapper based this child's entire lifeupon a singular lie, that was repeated to the point that the child was mind raped into believing it, even when the light of truth was shone in her face.
What do I think should be done? Frankly, I believe that cases like this are why Capital Punishment should never be taken off of the books. What that kidnapper did, in my opinion, was worse than rape.
