First off, 'it' is a she. Am reading blog and info on the condition--this is very interesting and I've never heard of it before. Shall no doubt post more later. Question though, what kind of ethical situation do you feel this applies to? What do you have in mind for the discussion?
Edit: Wow, that is... I don't even know what that is.
Reading this blog, and info about the disorder, I think I don't feel bad for the little girl actually. I feel sympathy, yes, but not a lot of sadness and it does not seem depressing to me. Apparently she can't feel pain and she's obviously very loved and well taken care of. True, she won't live a normal life, and maybe she won't live very much longer, but so long as her mother has no regrets I think things will be okay.
I wonder about her behavior--some research on the web leads me to think perhaps she is the only child with her anomaly to have lived so long. Clearly she does have some of a brain. Stroke victims who have lost portions of their brains often see other portions taking up the functions of the dead parts--perhaps with so much stimulation, something similar is going on for Faith? I hope so. Her mommy may hear her speak one day, if that is the case.
I guess I'm split-minded about things like this. I honestly don't know what I would do if I found out my child had that condition, but I admire the way Myah is living with her daughter, obviously treasuring every moment of it. More power to her.
Never thought I'd say this, but I'm rooting for Faith.
