Formula Used

50th percentile: Average height for your baby's age
25th percentile: Below average height
75th percentile: Above average height
Below 3rd percentile: May indicate potential growth concerns
Above 97th percentile: May indicate rapid growth

Note: Percentiles are based on general population data. Individual variations are normal and not always cause for concern.
