Free Baby Growth Simulator
Baby Growth Simulator helps you enter age, sex, height, weight, and head circumference, then estimate where each measurement sits on a birth-to-24-month growth curve. Save repeated records to see whether height and weight trends feel steady over time.
Private in your browser, with local records and calm reminders to ask a doctor about unexpected patterns.
Start Baby Growth Simulator here: enter one record, add more over time, and compare estimated height, weight, and head circumference percentiles with a simple trend view.
Enter the latest measurement, then save the record. Baby Growth Simulator keeps records in this browser so normal page visits stay clean.
Share the Baby Growth Simulator page. Baby measurements stay local unless you choose to copy a text summary.

Saved records show whether height and weight move smoothly over age.
The last two records estimate recent growth speed and percentile-band movement.
Records stay in this browser and can be cleared any time.

Growth charts are screening references, not a diagnosis. Measurement technique, prematurity, feeding, illness, family pattern, and clinical history all matter. Contact a doctor promptly for poor feeding, dehydration, weight loss, sudden drops, or any concern that feels urgent.
Baby Growth Simulator is educational and uses reference curves for birth to 24 months. It cannot diagnose growth concerns; ask a pediatric clinician about unexpected results or symptoms.
Baby Growth Simulator turns everyday measurement notes into a calmer view of percentiles, saved records, and height and weight trends.
Baby Growth Simulator starts with age in months, sex, length or height, weight, and head circumference, then estimates each percentile using reference curve math.
Baby Growth Simulator lets you save repeated records locally, draw height and weight trend lines, and notice whether growth speed stays broadly consistent.
Use Baby Growth Simulator as a gentle tracking aid, then bring questions or unusual patterns to a pediatric professional.
Measure age, sex, length or height, weight, and head circumference as carefully as you can, then review the estimated percentiles.
Add each visit or home measurement so the trend line shows whether height and weight are moving steadily over time.
Treat very low, very high, or fast-shifting percentiles as a prompt to ask a doctor, not as a diagnosis.
If your baby has symptoms, feeding trouble, dehydration signs, or sudden weight changes, seek medical care instead of relying on Baby Growth Simulator.

Answers about Baby Growth Simulator percentiles, growth curves, saved records, and when to ask a doctor.
Baby Growth Simulator uses LMS growth-curve parameters for birth to 24 months, then converts each height, weight, or head circumference measurement into a z-score and approximate percentile.
No. Baby Growth Simulator is an educational reference only. A pediatric clinician can interpret growth with exam findings, birth history, prematurity, feeding, illness, and measurement technique.
Growth is usually interpreted as a pattern over time. Baby Growth Simulator saves records locally so you can see whether height and weight trends are broadly steady instead of focusing on one number.
Ask a doctor about unexpected very low or very high percentiles, fast percentile shifts, weight loss, poor feeding, dehydration signs, developmental concerns, or anything that feels urgent.
Use Baby Growth Simulator to estimate baby growth percentiles from age, sex, height, weight, and head circumference.
Save repeated Baby Growth Simulator records locally to watch height and weight trends, then ask a clinician about any unusual pattern.
Baby Growth Simulator is free, private in your browser, and for reference only.
