Your baby's size and weight
It is important to know that each fetus has its own development pace, and only your gynecologist can confirm that your baby is healthy.
When you have your ultrasound appointment with your doctor, they will calculate the approximate height and weight of your baby. The fetus is measured from head to heel. These are the average measurements that you will receive.
It is estimated that the baby weighs and measures:
- Between 0.03 and 0.19 in during the 1st month of pregnancy;
- Between 4 and 5 in and between 0.24 and 0.44 lb during the 4th month of pregnancy;
- Between 15 and 17 in and between 3.7 and 4.8 lb in the 8th month of pregnancy;
- Between 17.7 and 19.7 in and between 5.2 and 7.2 lb before term.
