Charted against the WHO growth standards
A baby growth chart on the WHO standards, with the percentile.
The baby growth chart draws your baby’s own line over the WHO growth standards, for boys and for girls, birth to five years. Your baby’s sex, set when you add them, picks the right set. The chart shows the latest percentile, and each entry in the history underneath shows its own.
- Weight, height and head circumference, each with its own tab and its own WHO curves.
- Your baby’s percentile at the age of each measurement.
- Nothing predicted, nothing projected. The only lines on the chart are the WHO curves and your baby’s own.
- kg or lb, cm or in. Change units in Settings and the chart follows.
