Before the pattern, there's just a hunch.

You've cut out the strawberries, then the dairy, then put them back. Some nights are fine. Some nights aren't, and there's no thread to pull, just a worried kid and a guess. BellyMystery doesn't diagnose anything. It just remembers what you can't, so the next flare-up has evidence behind it instead of another guess.
