You know I was with her until the 9 children thing. Hate to say it, but shit happens and people die even when everyone behaves responsibly. There's always that chance that the moment you blink that baby will lunge for a wall socket, and keeping perfect vigilance 24 hours a day while still doing things that let you provide for your child is impossible. You can minimize the risk but every once in a while, a responsible, intelligent, caring mother is going to have a dead baby. The problem here is that the implication she is making is that her ability to care for her kid is compromised by the number of children she has. This is not acceptable. However, I AM willing to grant her some leeway insofar as she just lost her beloved child and is desperate for an explanation, and maybe she isn't at her best for explaining things. I can have pity for that.
Of course the real sticking point here is that it sounds like she left her child in a dangerous swimming pool, and leaving a child like that is unacceptable. But then again, there's nothing to be done about it now, im sure it seemed completely reasonable at the time, and she has to live with that mistake. What else can, or should, we stack on top of that?
