Built for careful parents

About BabyCalculator

BabyCalculator provides free, privacy-first calculators and readable guides for baby growth, feeding, sleep, pregnancy dates, and everyday care decisions.

Our mission

We help parents turn small measurements and dates into clear next steps without making the experience feel clinical or overwhelming.

How our tools work

Where possible, tools use public WHO, CDC, national immunization, and pediatric reference concepts. Other daily-care tools use transparent formulas and clearly labeled educational estimates.

What we are not

We are not a medical provider. Results are designed for family planning and conversations with clinicians, not for diagnosis or emergency decisions.

Editorial and review policy

We prefer primary sources from WHO, CDC and national health authorities. Every health-data page records its source and review date, and material updates are checked before publication.

Growth references and national vaccine schedules are reviewed at least annually and whenever an issuing authority publishes a material change.

BabyCalculator is responsible for the site’s calculations and summaries. Corrections can be sent to the contact address below.

What we value

What we value

Privacy first

Most calculations run in the browser and do not require accounts or personal profiles.

Readable explanations

Every tool is paired with guidance, result interpretation, references, and safety notes.

Parent-centered design

The interface is calm, scannable, and made for tired parents who need useful answers quickly.

References and editorial approach

  • WHO and CDC growth chart concepts are used for growth-related calculators where applicable.
  • Vaccine pages are educational summaries and should be checked against your local official schedule.
  • Care and feeding tools explain their assumptions so parents can understand the limits of each result.
