Oye...It's crazy. Ruby has been consistently sicker this week than when she was going through chemo. How is that possible? (Actually, parents of kids who have fought cancer would not be surprised.)
Ruby has been on and off congested a lot this spring, due to pollen/allergies. At one point they worried she would develop an ear infection, so they gave her antibiotics (April). This week, she ran two random fevers that went away with one dose of Tylenol, not to return until the following day at fever o'clock (that's 5PM). After two days in a row of that, coupled with her sleeping in (unlike Ruby), I took her to her pediatrician's office Thursday morning. They confirmed that her lungs sounded fine, and her ears were clear, but with the blood tinged nose-mucus and puffy eyes, they suspected a sinus infection.
I did call the pediatrician again yesterday to inquire if we should come back in. They assured me that she needed a few days of antibiotics under her belt to see an improvement. If she is still not turning around by Monday, come in. Her energy is down, but she has spurts through the day where she acts fine, plays like her usual self, and (until yesterday around noon), ate at least as well as usual.
