Terms of Use

Last updated: June 2026

By using BabyPercent (babypercent.com) you agree to these terms. The site is provided free of charge, "as is," for general educational purposes.

Medical disclaimer

BabyPercent is not medical advice. The percentiles, averages and milestones shown are reference values intended to help you understand your baby's numbers — they are not a diagnosis and cannot replace your pediatrician. Growth charts are one tool among many, and only a qualified health professional who has examined your child can interpret them in context. Always consult your pediatrician about your child's growth, feeding, development or health. In an emergency, call your local emergency number.

Accuracy of data

The values are reference averages modeled on WHO-style growth standards for ages 0-24 months. They are approximations for general understanding and may differ from the official charts your pediatrician uses. We make no guarantee of accuracy and are not liable for any decisions made based on this information.
