On Wednesday afternoon I got a call from Lily's daycare telling me she had a fever and I needed to go pick her up. I headed down there and got the poor little thing, who was definitely not herself. She had a fever and was very fussy -- which is quite unusual for her. She didn't want to be picked up, held, or touched. I brought her home and took her temperature, then read the fever section in What To Expect the First Year. I stripped Lily down to her diaper and wiped her down with a lukewarm washcloth. Her temperature went up a little more, so I called her pediatrician. He said I should keep her cool, give her some baby Tylenol, and bring her in if her temp got to 104 or if she cried and couldn't be consoled. (It peaked at 102.) I called Foster and asked him to bring us some Tylenol (it was way too hot to try to take her out with me to get some, and Emily was out seeing the new Harry Potter), and he came over just in time for me to give her a dose and put her to bed for the night.
The next morning her temperature was still pretty high and she was still cranky, but she got another dose of Tylenol. I worked from home all day to keep an eye on her, and luckily the fever went down by mid-day.
Today she was back in daycare. Her fever is gone but she's still a little more fussy than usual. Foster wants me to take her to a BBQ tomorrow, but given that it's going to be nearly 100 degrees, I'm not sure if that's going to happen. If she's still fussy, I might take her in to see the pediatrician. A coworker told me her baby was like that when she was Lily's age, and it turned out to be a bladder infection that got diagnosed so late that it had turned into a kidney infection, and now her daughter has chronic kidney inflammation. We definitely don't want that.
