YummyYucky tracks the whole baby day: feeds, sleep, diapers, first foods, and milestones. It reads your baby's own rhythm to flag the next nap and a reasonable bedtime, free. 1000+ food guides and a free allergen watch. Parent-funded, not data-funded: no ads, no data selling. Safety is never behind a paywall: allergen radar, watch window, and reaction logging are free on every plan. Plus adds your care team, keepsakes, and adventurous eating, and pays for itself on diaper and formula deals.
