It is very difficult to give birth to a baby with a lot of weight in a natural way. Therefore, even before the baby is born, expectant mothers want to know the weight. There are various methods for calculating weight, including ultrasound and ultrasonography. By touch, the doctor can tell about the weight of the unborn child only approximately.

Instructions
Step 1
With the help of an ultrasound examination, the weight is determined by the circumference of the head with an accuracy of 0.5 kg, but if the child is poorly visible, the specialist may make a mistake with the calculations. It is best to calculate the weight of the unborn child at 32 weeks.
Step 2
One of the most famous methods is the Lebedev method. To calculate, the height of the uterine fundus is multiplied by the girth of the abdomen and as a result, an approximate number of grams of the fetus is obtained.
Step 3
Many women believe that the size and weight of the unborn child can be compared with the size of the tummy, however, in nature there is no standard for the belly of a pregnant woman. It can be small, large, wide, or sharp. The size of the belly depends on the weight, height and breadth of the mother's bone. A high fetal weight can be associated with a high pre-pregnancy weight and the height of the mother.
Step 4
Determining the weight of the unborn baby is also associated with the purchase of the first clothes, because buying a standard size can make a mistake, since children are born with a weight of both 2.0 kg and 4.5 kg.
Step 5
Another popular method for calculating the weight of an infant is the Stroykova method. To do this, the weight of a pregnant woman is divided by the number of a constant, which is taken into account the weight. If a woman weighs 50 kg, then the constant is 15, if the weight is 51-53 kg, the constant is 16. Every 2 kg of additional weight is equal to one more unit of the constant. Then the circumference of the tummy is multiplied by the height of the fundus of the uterus, both sums are added and divided by 2. The result is obtained with an error of 200 grams.
Step 6
At 38 weeks of gestation, the weight of the child can be determined at home on your own using a regular centimeter. Lying on the bed, you need to grope for the upper edge of the pubic bone, apply a centimeter and stretch it along the midline to the upper edge of the uterus. The result must be multiplied by 100, which will be the approximate weight of the child in grams.
Step 7
If the baby is very large, it is necessary to discuss the caesarean section with the doctor in advance, read the literature about this operation and prepare psychologically. A caesarean section is also done if the baby is not properly positioned.
