"How do you explain that she did not know that she had a dead baby in the back seat of her Hot car when she got in to it at the end of her work day?"
I'm not in this woman's brain, but I'm sure she didn't look in back because she didn't expect the baby to be there. And the seat would have been turned around backwards because of the infant's age, which would tend to hide it.
I apologize for persisting in discussing this tragedy. It was just such a useless waste of life that makes me angry. Perhaps we need a Government Ad to run on all radio stations regularly - "Do you know where your baby is" to bring the gravity of this sort of situation home to new parents. I can understand how a person, especially a tired working mother of a five-month old, getting ready for work, getting her baby ready for daycare, driving to work while thinking of her day's duties, and by-passing the stop at day care.
Obviously, our hearts go out to her and the baby's father.
Since so many on this thread have accepted the inevitibility of this type of occurence, I think more publicity needs to be given to the possibility, so that new parents get into the habit of thinking about their baby first every time they are driving.
