Weight standards by World Health Organization
World Health Organization has set some standards for the weight of babies. These weight standards by World Health Organization determine whether your baby’s weight is normal or more or less than the WHO standard.
According to World Health Organization, most babies gain one pound in their weight each month.
Thus, the average weight of a baby girl at the age of 6 months is 16 pounds 2 ounces, equal to 7.3 kilograms. Therefore, most of the babies double their weight till the period of 6 months. For a baby boy, this weight is 17 pounds 8 ounces which is equal to 7.9 kilograms. In the same way, at the age of one year, babies triple their weight.
The weight of an average one-year-old baby girl is 19 pounds 10 ounces, equal to 8.9 kilograms, and the weight of an average one-year-old baby boy is 21 pounds 3 ounces, which is equivalent to 9.6 kilograms.
Weeks of pregnancy
The standard rule regarding weeks of pregnancy is that if your pregnancy has lasted more than the regular weeks of pregnancy, in that case, the baby born has gained more weight.
On the contrary, if the weeks of your pregnancy were less in number than the regular weeks of pregnancy, then the baby has less weight than the normal baby weight.
By the age of 1 year, the baby gained less weight than the normal baby weight of 1 year.
Smoking and Gestational diabetes of mother
Smoking and gestational diabetes of mother is another important factor. If a pregnant mother is habitual of smoking, then all her babies will be less in weight and low in nutrition status.
Smoking mother is extremely dangerous for the newborn. Mother has to get rid of this habit in every case. Otherwise, the baby’s weight will always be less than the normal weight of babies, continuing till later ages.
If the mother was normal, but during pregnancy, she got diabetes. In that case, the health of the newborn was seriously affected. Mother and baby both then faced severe health issues. The weight of a newborn is less than the weight of an average normal newborn baby.
The gender of your baby is also important. According to standards, the weight of a newborn baby girl is always less than the weight of a newborn baby boy. In the same way, by the age of 1 year, the weight of a baby girl gains less weight than the weight of a 1year old baby boy.
Family History
Family history is another important consideration regarding the weight of babies. In some families, everything is normal, but the weight of babies is less than the normal weight of babies.
On the other hand, some families have obese or bulky babies. This runs in families. If a family has the genetics of overweight and underweight, then the same thing runs in babies.
Multiple Pregnancies
If a mother got multiple pregnancies pregnant, then the weight of newborn babies will be less than the average normal weight. The same thing continues till the 1-year-old baby. 1year old baby gains less weight than the 1year normal baby because of frequent pregnancies of the mother.
In comparison, a 1st baby of a mother has no issue like this. The weight of that baby is normal according to standards.
This is a normal standard chart of babies’ weight. The weight of both girls and boys is shown in this chart according to their ages.

Conclusion
In the end, dear, if you are worried that your newborn’s weight is not according to this standard weight, keep in mind that minor variations exist. Don’t get panicked by slight variations. These are the standards that are taken in ideal conditions.
However, if the variations are large, then the best solution is to contact a well-registered pediatrician in your town as early as possible. A pediatrician can help you to know what is the average weight for a 1-year-old better than anyone else.
I recommend you to check your baby periodically with registered pediatricians for the safe side. Keep your baby healthy, and just enjoy each moment of parenthood!
