FAQ

Yes. All calculators and trackers are completely free to use. We support the site through advertising and occasional affiliate links. We will never charge for access to the core tools.

No. All data is stored locally in your browser using localStorage. Nothing is sent to our servers. Your feeding logs, symptom records, and growth measurements never leave your device. Clear your browser cache and the data is gone.

Our Formula Calculator and Growth Chart both include preemie correction modes that adjust for corrected gestational age. However, premature infants often have specialized nutritional needs that go beyond what any online calculator can provide. Always follow your neonatologist's guidance for preemies.

Our calculations are based on standard pediatric nutrition guidelines (150 ml/kg/day for newborns, 120 ml/kg/day for 1-6 months, etc.). They provide a reasonable estimate for healthy, full-term infants. But every baby is different. Growth spurts, illness, and individual metabolism all affect actual needs. Use the calculator as a starting point, not a prescription.

Yes. Every tool includes an export function that generates a CSV file or plain text summary. This is perfect for bringing to pediatrician appointments or keeping your own records. Since data is stored locally, exporting is the only way to back it up.

No. We are brand-agnostic. Our tools work with any standard infant formula. We do not accept payment from formula manufacturers and do not endorse specific brands. Our articles share personal experiences but never claim one brand is universally better than another. The right formula depends on your baby's individual needs.

Yes. Use the Export or Copy functions in any tool to generate a shareable report. You can email the CSV file, paste the text into a message, or print it for appointments. Since data stays on your device, sharing is manual — but that also means you have full control over who sees it.
