FAQ – Baby Growth Tracker
What are growth percentiles?
Percentiles show how your baby compares to others the same age. The 50th percentile means average — half of babies weigh more, half weigh less.
Should I worry if my baby is below 50th percentile?
Not necessarily. Consistent growth along any percentile curve is healthy. Sudden drops or jumps may need attention.
