What does a percentile mean?

A 60th percentile for weight means your baby is heavier than 60% of babies of the same age and sex. There's a wide healthy range — the trend over time matters most.

Which charts do you use?

The official WHO Child Growth Standards (0–24 months), the international standard for healthy child growth.
