Why Track Your Baby’s Growth?
The first 1,000 days of a baby’s life are crucial for their physical and mental development. To ensure they are getting proper nutrition, pediatricians use the standardized World Health Organization (WHO) Growth Charts. This calculator uses the WHO’s 50th percentile data to give you the average weight and height for your baby’s age and gender, helping you track their health right from home.
Frequently Asked Questions
What if my baby’s weight is lower or higher than this average?
Don’t panic! This calculator shows the 50th percentile (the exact middle average). It is perfectly healthy for a baby to be in the 25th or 75th percentile depending on their birth weight and genetics. Always consult your pediatrician for a proper medical assessment of your baby’s unique growth curve.
Why are boys and girls calculated differently?
Biologically, infant boys tend to be slightly heavier and longer than infant girls on average. The WHO created separate, gender-specific growth charts to provide the most accurate health assessments possible.
