We’re now suspecting that Ingrid’s fever, diarrhea, fussiness and lack of appetite may be due to a new tooth. I am pretty sure I saw a teensy strip of white where the next tooth should come. But she doesn’t like us poking around in her mouth so this is still just a guess.
Myself: the intractable bug is beginning to yield; I think I’ve narrowed down the conditions where it occurs. Unfortunately those conditions would occur in 99% of all cases if this was rolled out to users. And I still have no idea how to fix it.
