Yesterday a new question popped into my head:
Did he starve to death, or was he asphyxiated?
I could go through the autopsy report again, I could put myself through the trauma of calling my doctor and forcing him to talk to me about it, I could do tons of reading around umbilical cord accidents, seek out other parents to connect with, read blogs, get as close to an answer as I can, do all the usual things to fill in the horrific blanks.
But in the end, he will still be dead. Forever.
