Nope, not in a million years can I see any justification to this. Not at all. I have 3 kids and there was never a moment that I forgot about their existence. You would have to believe that her daughter never crossed her mind even one time in that 8 hour period. Impossible. If I ever did forget my kids in their car seats- which I wouldn't - for the love of ****ing god, at some point during my day I would have thought of them, and then realized that I didn't remember taking them to daycare or their nannies, and that would have jolted me to the point I would run out and see where they were.
This stupid bitch. I hope this haunts her until the day she dies. I'm sorry for not being sympathetic, but as a mother, to have this happen is as likely as finding Elvis Presley standing in my closet.
