Roseola

My son has had a fever off and on since yesterday afternoon. Highest it’s been is 39.7 degrees and it goes down with Tylenol or Advil. Had a virtual appt with a pediatrician today and was told it sounds like roseola. Has anyone else experienced this with their LO’s? How long did the fever last before the rash broke out? Besides being tired and wanting mama, plus the fever, he has no other symptoms. He’s nursing a lot, peeing normally and has pooped 2 times today. Woke up more often last night to nurse which is ok with me at this point! But man, as a first time mom with a 6 month old, during this pandemic, my anxiety is through the roof. 😩😭

My poor little baby 😭
