How to Use the Baby Growth Chart
- Use the chart regularly to track growth trends, not single readings.
- Measurements should ideally be taken at the same time of day.
- Growth is assessed over time, not on one value alone.
What Do Percentiles Mean?
Percentiles show how your baby’s growth compares with other children of the same age and gender.
- 3rd Percentile: Lower range of normal growth
- 50th Percentile: Average growth for age
- 97th Percentile: Upper range of normal growth
A baby growing steadily along any percentile line is usually considered healthy. Sudden drops or rises may need medical attention.
WHO Percentile Table (Boys Example)
| Age (months) | 3rd % | 15th % | 50th % | 85th % | 97th % |
|---|
A baby growing steadily along any percentile line is usually considered healthy. Sudden drops or rises may need medical attention.
When Should Parents Be Concerned?
- Weight consistently falls below the 3rd percentile
- Sudden weight loss or very slow weight gain
- Baby seems lethargic, feeds poorly, or has developmental delays
