You didn't mention if they considered DH the dermalogical "sister malady" to Celiac. The best way to tell is that it will be exactly symetrical. For instance, I had bumps that were mirror images of the ones on the opposite hand, knee, cheek etc. My Dr. said gluten can be in the systems for up to a year after it is ingested. I had been gluten free for over 6 months. I don't know about the fever. I din't notice fever and haven't read about babies and DH. Good luck.
