Average Baby Weight by Age (WHO)

Comparing a rough estimate against the growth-chart median helps you see if your baby is tracking normally between checkups. Wide healthy ranges exist around these medians.

AgeBoys (avg)Girls (avg)
Birth3.3 kg (7.3 lb)3.2 kg (7.0 lb)
1 month4.5 kg (9.9 lb)4.2 kg (9.3 lb)
3 months6.4 kg (14.1 lb)5.8 kg (12.8 lb)

WHO median values. Healthy babies vary widely around these figures. Only your pediatrician can assess growth properly.

Casual Baby Weight Monitoring Between Checkups

Pediatrician visits are typically scheduled weeks or months apart, and parents often wonder about their baby's weight between appointments. Our AI baby weight estimator provides a rough estimate from a photo, satisfying your curiosity and helping you spot potential concerns worth discussing with your doctor.

Not a Medical Device: Use with Appropriate Expectations

This tool is designed for casual reference only and should never replace proper medical weight measurements. Baby health decisions should always be based on measurements taken by healthcare professionals using calibrated medical equipment. Use our tool for fun, general awareness, and to track trends rather than for medical purposes.

Tips for Getting a Better Baby Weight Estimate

For the best estimate, photograph your baby lying on a flat surface or being held by an adult. Including a known reference object like a standard pillow or blanket helps the AI gauge size. Photos taken from the side with the full body visible tend to produce the most useful weight estimates.
