The male baby is 45.2-55.8cm long and weighs 2.26-4.66kg, while the female baby is 44.7-55.0cm long and weighs 2.26-4.65kg.
The baby's height and weight standards will vary according to the baby's gender. According to the evaluation standards of children's growth and development, the height and weight standards of newborns are: male baby's length is 45.2-55.8cm, weight is 2.26-4.66kg, female baby's length is 44.7-55.0cm, and weight is 2.26-4.65kg. ..
Anything whose height and weight exceed the standard 10% or less than 10% means that parents should adjust their baby's diet in time to improve their baby's development.

The standard weight scale of newborn's monthly growth shows that children's growth is very important and cannot be separated from their parents' careful care. Complementary and balanced development in all aspects is the main means for children's healthy growth. Let's share with you the standard weight table of newborn's monthly growth.
Comparison table of neonatal monthly growth standard weight 1
Characteristics of neonatal weight change
A newborn's birth weight reaches 2500 grams to 3999 grams, which is normal weight; Babies below 2500 grams mean low birth weight, and babies above 4000 grams mean giant children.
The average birth weight of a baby boy is about 3.3kg, and that of a baby girl is about 3.2kg.
After a newborn is born, it doesn't always gain weight.
Due to insufficient intake, meconium excretion, dehydration after leaving amniotic fluid environment and other reasons, infants will experience temporary weight loss, also known as physiological weight loss. Generally, it will drop by 3%-9%, drop to the lowest weight on the 3rd-4th day after birth, and then gradually rise, increasing by 30-50g every day, and then return to the birth weight on the 7th 7- 10/0 day.
If the weight loss exceeds 10% on the first10 day of birth or does not return to the birth weight, improper feeding or pathological factors should be considered.
Specific calculation method
The baby's weight grows fastest in the third month after birth, generally increasing by 600- 1000 grams per month. The baby's weight at three months is about twice that at birth.
The weight calculation formula is as follows:
1-6 months: weight = birth weight+month age ×0.7.
7- 12 months: weight =6+ months ×0.25.
You can also calculate whether the baby meets the standard from the monthly increase.
In the case of sufficient milk:
Weight gain in the first four weeks is about 1 15-200 grams per week.
You can gain weight 180-200 grams per week in the first three months.
4-6 months, the weekly increase is150-180g.
6-9 months, increase by 90- 120g per week.
September ~1February, increasing by 60 ~ 90g per week.
Calculated by weight gain multiple:
The baby's weight at 6 months is twice that at birth;
1 year, about 3 times;
At the age of 2, it is about 4 times;
At the age of 3, it was about 4.6 times.
In the second year after birth, the baby's weight increased by an average of 2500 ~ 3000 grams.
After 2 years old, the average annual growth rate is about 2000 grams, until adolescence.
Newborns can be weighed at 2, 4, 6, 9, 12 months after birth. 1-3 years old can be called 1 time for half a year; 3-7 years old can 12 months weight 1 times. This is normal if the weight curve is parallel to the standard weight curve.
After 6 months, you can add complementary food to your baby while breastfeeding to ensure adequate nutrition and make your baby's weight reach the standard.

1, neonatal weight gain standard
The baby's weight increased 180-200g per week in the first three months, 150- 180g per week in the fourth to sixth months, 90- 120g per week in the sixth to ninth months and 60 per week in the ninth to tenth months. According to the multiple of weight gain, the baby's weight at 6 months is .2 times that at birth, about 3 times at 1 year, about 4 times at 2 years old and 4.6 times at 3 years old.
2, newborn monthly weight gain table
According to the Reference Standard for the Growth and Development of Children under 7 in China issued by the Ministry of Health, the standard weight of a baby boy at birth is 6.6 kg, and that of a baby girl at birth is 6.4 kg. 1 month later, the baby boy weighed 9 kg and gained 2.4 kg, while the baby girl weighed 8.4 kg and gained 2 kg. Compare this standard data.
3. The law of neonatal weight gain
The average daily gain of newborns is 30-40g, the average weekly gain is 200-300g, and the average monthly gain is 600- 1200g, but there are individual differences. As long as the baby's weight at 3 months is twice that at birth, it means normal.
Generally, the physiological weight will be restored in one week, and the baby will gain little weight. Coupled with the error between different scales, the error of weighing method, and the influence of some comprehensive factors, it is normal for the baby not to gain weight for the time being. Now feeding the baby well is the key.

0-March: the monthly increment is 800-1000g.
April-June: increase by 500-600g per month.
July-65438+February: the monthly increase is 200-300g.
1-2 years old: increase by 2.5-3.5 kilograms every year.
2 years old-adolescence: 2 kg per year.
Second, the factors affecting the baby's weight
1, Maternal and Child Health
The health of the mother or baby will directly affect the baby's weight. When the mother's milk secretion is insufficient, or the baby suffers from certain diseases, it is easy to be underweight. When the baby is overnourished, then the baby will naturally be overweight.
2. Sleep state
Sleep quality is very important for growing babies. A baby who sleeps well grows faster and naturally gains weight. Therefore, it is necessary for parents to create a good sleeping environment if they want their baby to gain weight.
3, calorie intake
Breast-fed babies, breast-feeding methods and breast-feeding times will affect their nutrition and calorie intake; Artificial feeding, feeding time and frequency will also affect the baby's calorie intake, and then cause the baby's weight abnormality.
4. Other factors
Mothers who don't pay attention to their own aftercare during pregnancy will also affect their baby's weight gain. Such as the mother's first birth age; For example, the length of the pregnancy cycle and so on.
The standard of baby weight gain is an average of normal baby growth and development. If the baby's weight growth is within this range, then the child's growth and development is normal, but if it is very different from this standard value, then the child's growth and development may have some problems. As parents, we must pay attention to this standard value and try our best to make the child's weight gain within the standard value range.
Infant weight standard reference table
When you are 3 months old, you can reach twice your birth weight.
The weight standard of 0~ 12 months infants is as follows:
1. The normal weight range at birth is 2.9 ~ 3.8kg for boys and 2.7 ~ 3.6kg for girls.
2. 1 month-old boys' normal weight ranges from 3.6 to 5.0 kg, and females' weight ranges from 3.4 to 4.5 kg.
In March and February, the normal weight of boys ranged from 4.3 to 6.0 kg, while that of girls ranged from 4.0 to 5.4 kg.
In April and March, the normal weight of boys ranged from 5.0 to 6.9 kg, while that of girls ranged from 4.7 to 6.2 kg.
In May and April, the normal weight of boys ranged from 5.7 to 7.6 kg, while that of girls ranged from 5.3 to 6.9 kg.
In June and May, the normal weight of boys ranged from 6.3 to 8.2 kg, while that of girls ranged from 5.8 to 7.5 kg.
In July and June, the normal weight of boys ranged from 6.9 to 8.8 kg, while that of girls ranged from 6.3 to 8.1kg.
In August and August, the normal weight of boys ranged from 7.8 to 9.8 kg, while that of girls ranged from 7.2 to 9.1kg.
9. 10-month-old boys have a normal weight range of 8.6~ 10.6kg, while females have a weight range of 7.9~9.9kg.
10 and 12-month-old boys have a normal weight range of 9.1~1.3kg, while females have a weight range of 8.5 ~10.6kg..
In general, the growth rate is the fastest in the first three months of infancy, and then it gradually slows down with the growth of months.
