The poor 6 year old has succumbed to the strep bug. Poor thing. I ended up with the same doctor that I had for the 2 year old. I had to ask him, again, what that "bruise-looking" thing was on the back of her throat. It's called a peticheal. Some kind of hemmorage thing that can be caused by viruses.
(I guess it can be a symptom of many other, horrible, things. The kind Doc warned me against Googling it.)
So, here's hoping that the rest of us make it through the weekend.
