How long after the Roseola rash appeared did your LO's fussiness stop? R had a fever from Wednesday night overnight until Sunday (started high at 103 but by Saturday/Sunday it was borderline 100.5) No fever Monday and then Monday night at bath time we saw the trunk rash. The rash is gone today but the fussiness continues (extremely fussy since Saturday). My older son had it but that was over 2 years ago and the details are fuzzy. Thanks!
