Baby growth charts plotted on WHO percentile curves
Baby growth charts in LifeWell plot the measurements you record onto the World Health Organization child growth standards. Monitor your baby's weight, length, and head circumference plotted against World Health Organization growth standards. Visualize percentile trends over time with interactive D3.js charts. A percentile describes where one measurement sits among many children; it is not a score and a low one is not a problem by itself. What matters clinically is the trend, and the trend is exactly what a chart shows and a single weigh-in cannot. Any concern about it belongs with your paediatrician.

Questions
Which growth standards does LifeWell use?
LifeWell uses the WHO Child Growth Standards, which are the international reference for children from birth to 5 years. These are the same standards used by most pediatricians worldwide.
How often should I record measurements?
For newborns, weekly weight measurements are common. After the first few months, monthly measurements are typically sufficient. Record whenever you have data from a checkup or home scale.
