Carson has a rash - on his stomach. S noticed it this morning and it's gotten worse tonight. I called Telehealth and they said it's most likely roseola, which is contagious BEFORE the symptoms appear. It doesn't seem to have affected his mood at all, he's not super hungry - but that goes in spurts anyways, so I wouldn't even call it a symptom.
Update - two days later, the rash is gone!
