Baby weight during pregnancy?

The real reply from the in-app AI advisor
During pregnancy, ultrasound measurements are the most common method used to estimate your baby's weight. Doctors calculate an estimated birth weight from measurements like head circumference, belly circumference, and thigh bone length.
Just to give you an idea:
- At 20 weeks, baby weighs about 300-350 grams
- At 30 weeks, about 1.3-1.5 kg
- At 40 weeks, roughly 3-3.5 kg on average
But every baby develops differently. Ultrasound estimates also carry a ±15% margin of error. Regular check-ups with your doctor are the most reliable way to track your baby's growth.
