The physical development of newborns before one year old is particularly important, and it is also an important measure of whether the baby is healthy, but it is not what the parents say, the bigger the better. What needs to be reminded is that there are individual differences among newborns, and each baby's size is also different.
In the standard of baby growth and development, a four-month baby 12 kg is a normal category.
Under normal circumstances, a baby weighs approximately 2500-3999 grams at full-term birth.
In the first 3 months, the baby’s weight gains about 180-200 grams per week; from 4 to 6 months, the weight gains about 150-180 grams per week; 6 to 9 months, the weight gains about 90-120 per week Gram; 9 to 12 months, weight gain is about 60-90 grams per week.
In the first six months, the baby’s weight is twice that of birth. At 1 year old, the baby’s weight is about 3 times that of birth. At 2 years of age, the baby’s weight is about 4 times that of birth. At 3 years of age, this value is about It is 4.6 times.
0-3 months: the first to lose the scale, the rapid growth afterwards
Generally speaking, the weight of newborns increases the fastest in the first three months of birth, and increases with time Increase, the faster the overall weight gain, and the younger the younger, the faster the weight gain. Babies aged 0-3 months can increase their weight by 180-200g per week.
However, babies within 3 days of birth will lose their scales. Mothers don't need to worry too much, it is normal. Because in the first few days of birth, meconium and water will be lost, and milk intake is still very small at this time, so the weight will temporarily drop, which is also called physiological decline.
Three to five days after birth, it may be reduced to a minimum, and the weight loss can reach 6-9% of birth weight, and it is normal to not exceed 10%. Generally, the weight can be restored on the seventh to tenth day.
after a brief period of weight loss. The baby's growth rate will reach about one or two per day, and the full-month baby will gain two or three pounds of weight compared to when it was born.
It should be noted that for a full-term baby, the baby's weight is usually about six catties, and the baby with a range of five to eight catties should be normal. Individual babies who are underweight or overweight should follow a doctor Suggestion,If you are healthy, it will be fine.
4-12 months: slow growth
is the first peak period of baby development before one year old. The weight can be increased up to 3 times that at birth. If the baby's weight at birth is 7 catties, it can reach 21 catties at one year old.
As mentioned above, although the growth rate within one year of life is the fastest, it is also staged, not at an even rate. The younger the baby, the faster the weight gain, and as the age grows, the weight will become slower.
and the baby of 4-6 months can grow 150-180g per week; the baby of 9-12 months can grow 60-90g per week. 12 catties in 4 months is normal. If the birth weight is 8 catties and the increase of 1 catty per month, it will be 12 catties.
is summarized as follows:
1, 0-3 months, rapid weight gain, an average weight gain of about 1.5 kg per month;
2, 4-6 months, weight suspension period, weight per month can be average Increase 1-1.2 kg;
3, 7-9 months: the weight continues to increase slowly, an average increase of 0.6-0.8 kg per month;
4, 10-12 months: the average weight increase per month at this stage is 0.3 -0.5 kg.
So in terms of multiples, a six-month-old baby gains weight twice as fast as a birth; a one-year-old baby is three times older; a two-year-old baby is four times as large; and a three-year-old baby is about four times. Point six times.
In the following year after birth, the baby's weight gain is about 2.5-3kg on average.
So for some mothers who asked: "How come the baby grows to 4 months, it seems that it doesn't grow anymore?" "Why doesn't the weight change this month?" The answer is not that the baby's weight no longer grows, it just grows. The speed is slower than before, and most of them are normal. On the contrary, the longer and faster is an abnormal phenomenon, and we need to be vigilant.
But there is another situation, that is, some children do have the problem of excessive weight gain. To summarize the following aspects:
1. Underdevelopment in the uterus
When these babies are still in their mothers,Due to various reasons, it leads to stunted growth. Although born at full-term, the weight is not up to the standard, 2.5kg below the average level, and it becomes a full-term baby.
In this case, the problem may be the imperfect development of various organs, weak digestion, small food intake, slower growth rate, and slower weight gain.
2. Acquired insufficient feeding
After the baby grows to six months, the nutrient breast milk that he needs can no longer be fully supplied, and supplementary food should be added to the baby in time, otherwise it will easily cause the baby to grow too slowly and gain slow weight.
For babies fed with milk powder, mothers also need to pay attention. If the milk powder is too diluted, the baby's nutritional intake will be insufficient, which will also cause developmental delays. Poor milk powder can also affect your baby's development.
3. Diseases
If the baby has diseases similar to the respiratory tract, digestive tract, heart, etc., it will also cause the baby's development speed to be too slow.
Important reminder: From the perspective of baby's health, mothers must protect their diet, sleep, and mood during pregnancy to ensure the normal development of the baby in the mother's body before giving birth to a healthy baby. If it is found that the baby is born Don’t panic after a series of illnesses, take your baby to see a doctor in time.
