Baby growth tracker with WHO reference curves
Baby Track lets you record your baby’s measurements and view them against WHO reference curves. Estimates are approximate and are here to help you follow the record, not to judge your baby.
What you can log
Record weight, length or height, and head circumference, with a separate history for each child. View your measurements on WHO reference curves, and compare several children’s curves side by side.
Where the reference comes from
WHO’s child growth standards describe growth from birth to five years under specified favourable conditions, drawing on a multicountry study. They are a reference, not a verdict on an individual child. [1]
Charts support professional assessment
The CDC explains that growth charts are one tool health professionals use, together with other information, to assess a child’s growth. Bring your recorded measurements to check-ups; interpretation belongs with your care team. [2]
Estimates are not measurements
Baby Track calculates approximate growth scores by interpolating between WHO reference points, and offers projections of future measurements and clothing sizes from your recorded values. These are planning estimates, not validated clinical predictions or a guaranteed growth trajectory.
What this tracker does not do
- It does not diagnose growth problems or replace measurements taken by professionals.
- Projections are estimates and should not guide feeding or treatment decisions.
- It does not say what your baby should weigh or how fast they should grow.
Questions about Baby Track
Which growth references does Baby Track use?
WHO reference data for weight, height and head circumference, with approximate calculations between the published reference points.
Can I trust the growth projections?
Treat them as approximate planning aids. They are extrapolations from your recorded values, not clinical predictions.
