Food transitions fail most often when you log “switching food” but omit stool and appetite shifts—there’s nothing to reconcile later.
Capture roughly three pre-switch days: intake tier or grams, stool form, and baseline energy; during transition track blend ratios day by day across 7–14 days.
If vomiting or soft stool appears, record clock time and whether deworming, treats, or outings happened the same day—otherwise attribution drifts.
A minimally viable note is still useful: “ratio changed on date X + one stool sentence”—better than a whole week of vague text.
