Percentile reference data is sourced from the WHO Child Growth Standards (0–24 months) and the CDC Growth Charts. This tool computes percentiles mathematically from these public reference tables. It is an educational planning tool, not a medical device. It does not diagnose, screen for health conditions, or replace a pediatrician's assessment. A single percentile reading does not indicate a health problem — growth trajectories over time matter more than any single data point. If you are concerned about your baby's growth, feeding, or development, speak with your pediatrician.
