I don't know about the baby who was left in the car for hours, but unless there are seriously mitigating circumstances, I'm afraid I would blame the parents. Who leaves their baby unattended in a car for hours? 
In any case, I agree that this scenario is totally different from that one. But I still think it's weird that both parents left without checking where their daughter was.
It doesn't seem as if she has been traumatised by the experience anyhow. But the press will have a field day! :)
