A high fever, irritability, a rash and internet research prompted me to take Olivia to the ER (all walks in were closed that long weekend) just to confirm that she had Roseola (since I had already diagnosed her - love the internet).
Yes, in fact she did have Roseola and all you can is keep them comfortable and wait it out. Olivia was really irritable for about 5 days (which is not like her at all) and I knew exactly when it left her system because she started to laugh again.
A few months later, while at a Naturopathic appointment, I mentioned that Olivia had had Roseola and the doctor clapped 'yay Roseola!'. Huh??? How come? As it turns out, it's a wonderful viral bug to get for overall immune building/exposure and once it's gone, there is a great growth spurt that takes place.
So, flip the coin around if your little one has or had Roseola ... it's a good thing!
Go figure.
