Growth Charts

The idea
Growth charts plot a child's weight, length and head size as percentiles by age and sex; the CDC recommends the WHO charts through age two.
In practice
A baby tracking the fiftieth percentile for months, then dropping across two lines.
Where people slip
A drop across percentile lines prompts a look for causes; a steady low line may reflect small parents.
