Child growth

Did you know?

Children don't grow at steady rates — they grow in spurts. A toddler might not change height for weeks, then grow half an inch overnight. Growth charts show percentiles, not ideals: a child at the 25th percentile isn't "below average" in any meaningful sense. They're simply shorter than 75% of children their age. The pattern over time matters more than any single measurement.
