I am so incredibly sorry for your loss. How terrible to lose a child.
There is an article here that I found online on SIDS that I think should be of some consolance. I see these types of articles from time to time and think that some of these doctors are out in left field scrambling for research dollars on research that won't go anywhere, but this one is very promising.
It is an Anesthesiologist (interesting...b/c he's not a Neonatologist), that noticed that infants that were later victims of SIDS whose hearing was tested prior to leaving the hospital, were showing a hearing loss in one ear...and you think, "Ok, what in the world does that have to do with SIDS?". What his research has found, is nothing short of astonishing.
I sent the article to my former Anatomy professor because it makes so much sense, I think this physician, if he can further prove his theory, will solve a mystery that has escaped doctors for years....and most importantly, that SIDS may not be preventable in the majority of cases
...which, if I were the parent, would be of some small comfort.
