The jury is going to be asked if she poses a threat to society. Answer: Yes. Left alone with another child, there is a substantial risk to that child's health.
The other question is whether there are any mitigating circumstances.
The question there is whether her mental health was a mitigating circumstance. Should she be punished less because of it?
That's a far more interesting question, and one I suspect the jury will take much longer to deliberate. My guess is that they will consider it a mitigating factor and sentence her to life instead of death.
However, the speed in which this jury returned a verdict didn't indicate that anybody was wavering as to whether she was morally culpable. And, ironically, a death sentence might be more merciful than life imprisonment for her.
I'm less certain about the punishment than I was about the verdict. I'd put maybe a 75% chance on NO death penalty.
