Any one know? Ava has a very high fever 104. We started her on Motrin but it didn't come down, so she got tylenol as well. I know it will make her Dexcom sensor go wonky, but is the whole sensor shot, or just while the tylenol is in her system? Right now she's in the ER with Daddy while I am home nursing the baby. She had ketones of 1.3 as well. ARG. This is our first trip back to the ER since diagnosis.
