This infant food allergy tracker helps you spot patterns between formula brands and symptoms that your sleep-deprived brain would otherwise miss. Log rashes, digestive issues, respiratory symptoms, and behavioral changes with severity ratings. The visual timeline shows when symptoms cluster, and the formula comparison feature lets you filter by brand to see if one particular formula is causing more problems than others.
The symptom timeline chart plots each logged entry on a time axis. The vertical position shows severity (1-10), and bubble size increases with severity. Color coding separates symptom types: red for skin reactions, orange for digestive, blue for respiratory. When you see a cluster of red bubbles after switching to a new brand, that's data you can take to your pediatrician.

The tracker includes all these categories plus an "Other" option for symptoms that don't fit neatly. The export function generates a doctor-ready report with dates, severity, and notes — no more trying to remember "when did that rash start?" during a 15-minute pediatrician appointment.
