Looks like the little guy had roseola last week – he had all the symptoms:

Christian had a fever for three days and then when the fever broke, a rash quickly developed over his torso, creeping up his neck and down into his crotch area. The rash did not appear to itch or bother him in any way. He also had mild diarrhea. Two days later the rash disappeared. Everything passed through without any medical treatment, but he was extremely fussy and didn’t sleep well, and he needed lots of comforting and nursing. He had no appetite for regular food.

All told, we were in the house for five days. And I have no idea where he got it, because the incubation period can be as long as ten days.

However, roseola is supposed to be very common, with most children contracting it before entering kindergarten. It generally affects children between the ages of 6 months and 2 years, with the average age being 9 months. It is considered a mild illness. The only real hazard is posed by high temperatures. We never actually took Christian’s temperature, but watched his behavior very closely. Meaning he was hot, but never so much that he became lethargic or strange. He was just his normal self, but a grumpy, cranky version of himself.

I would’ve taken a picture, but I didn’t realize that it might be helpful to see what his rash looked like at the time.
