I still don't know how old she actually was. If, when she was born, and during her first few months she didn't really have any symptoms, no doctor would check for an autoimmune disease, in my opinion. If she started showing symptoms and they took her to the doctor, there are records for sure, if she was ever diagnosed with anything I have a hard time believing that there were not extensive medical records. The thing is, autoimmune diseases are really hard to diagnose, specially in the early stages, more often than not, the symptoms come and go, sometimes people don't have any symptoms for a long period of time and then, boom there's another flare and the symptoms are back. So, if a kiddo is complaining about an headache but it eventually goes away, and a few weeks later it's the tummy that hurts but it also eventually gets better, but then the head is hurting again, I can see parents not really get super alarmed until something really bad happens. I wonder what the cause of death was.
