The standardized birth weight of newborn babies is around 2.8kg~3.8kg.
The average birth weight of male infants is 3.0-3.8kg and that of female infants is 2.8-3.6kg. The World Health Organization’s reference value is 3.3kg for male infants and 3.2kg for female infants.
The World Health Organization reference value is 3.3kg for male babies and 3.2kg for female babies. Currently, due to the nutritional level of pregnant mothers and other factors, the birth weight of babies increases slightly, and there are even individuals born with weights greater than 4.0kg.
The birth weight of a baby indirectly reflects the intrauterine growth of the fetus. As long as the weight is within the normal range and there are no other abnormalities, it does not affect the growth and development after birth.
