With the help of ultra­sound the weight is deter­mined by the cir­cum­fer­ence of the head with an accu­ra­cy of 0.5 kg, but if the child is poor­ly seen, the spe­cial­ist may make a mis­take with the cal­cu­la­tions. Cal­cu­late the weight future baby is best at 32 weeks.

One of the most­the weightone of the most com­mon meth­ods is the Lebe­dev method. To cal­cu­late the stand­ing height of the bot­tom of the uterus is mul­ti­plied by the girth of the abdomen and the result is an approx­i­mate num­ber of grams of the fetus.

Many women believe that size and the weight future a 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 weigh­ta, growth and breadth of mom’s bones. Large the weight fetus may be asso­ci­at­ed with greater the weightom before preg­nan­cy and moth­er’s growth.

Def­i­n­i­tion the weigh­ta future the baby is also asso­ci­at­ed with the acqui­si­tion of the first clothes, because buy­ing a stan­dard size you can make a mis­take, since chil­dren are born with the weightohm and 2.0 kg, and 4.5 kg.

Anoth­er pop­u­lar method for cal­cu­lat­ing the weight of an infant is the Stroyko­va method. For this the weight preg­nant woman is divid­ed by the num­ber of con­stants, which is tak­en into account the weigh­ta. If a woman the weigh­tum 50 kg, then the con­stant is 15 if the weight 51–53 kg — the con­stant is 16. Every 2 kg of addi­tion­al the weigh­tand are equal to one more con­stant unit. Then the cir­cum­fer­ence of the tum­my is mul­ti­plied by the height of the bot­tom of the uterus, both sums are added and divid­ed by 2. The result will be obtained with an error of 200 grams.

At 38 weeks preg­nant the weight the child can be deter­mined at home on their own using a reg­u­lar cen­time­ter. Lying on the bed, you need to feel the upper edge of the pubic bone, attach 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 approx­i­mate the weightohm of the child in grams.

If the baby is very large, you need 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.
