Fever Whiz assistant
Jack's highest reading today was 102.0°F at 4:10 PM. It has come down since — the last reading was 100.0°F at 7:30 PM.
The app suggests a 6 hour interval for this medicine. The last dose was at 2:00 PM, so the next-dose window opens around 8:00 PM.
Done — fever reducer, 5 ml is logged for Jack. ✓ You always get to confirm before I save anything.
It's not bad luck — the body's internal thermostat runs on a daily rhythm, dipping in the early morning and peaking in the evening, and a fever rides on top of that cycle. Our guide on night-time fevers explains it — and always check with your pediatrician if you're worried.
