Built for my own kid, then generalized. Combines a structured 28-day baby-led-weaning starter plan with a tracker for allergen introductions (one new allergen at a time, three days apart, the protocol pediatricians actually recommend). PWA so it works offline at the kitchen counter.
Domain-specific software lives or dies on whether you trust the rules baked into it. The bulk of the work was getting the protocol right and making the constraints visible to the user instead of hiding them.
