What this guide covers
Written for a parent holding the paper from the nurse: a page each on the growth chart and what crossing centiles does and does not mean, WHO versus national charts, mid-parental height, BMI-for-age and why adult BMI categories do not apply to children, head circumference, blood-pressure percentiles that depend on height, developmental milestone ranges and the "the range is wide" rule, hearing and vision screening outcomes, the paediatric laboratory ranges that differ from adults', correction for prematurity, and how to tell an ordinary spread from a genuine red flag.
Fourteen pages, every one ending at "bring this to the nurse".
How to use it
Use The numbers on your child's health check, explained as a structured learning path: begin with the vocabulary, follow the evidence map, and keep the uncertainty labels attached to claims as you compare sources.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
Search vocabulary in four languages
Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.

| Estonian | lapse kasvukõver protsentiil tähendus |
| Finnish | lapsen kasvukäyrä persentiili selitys |
| Russian | перцентиль роста ребенка что значит |
| English | child crossing growth centiles meaning |
