For example, when I took Bubu for vaccination, I heard a grandmother say, "My granddaughter's pants last year can still be worn this year, and they haven't grown much this year." The pants that were worn just right last year can still be worn this year, and the baby really doesn't grow fast. No wonder this grandmother is worried.
However, every baby has its own growth rhythm. Being shorter than others does not mean that development is backward. Then, what is the height and weight of the baby at different stages?
The Capital Institute of Pediatrics has released the 2020 edition of "0- 18-year-old children's height and weight standard deviation unit numerical table". Parents may wish to compare and see if their baby is within the standard value range.
What do you think of these two pictures?
Firstly, boys and girls are divided into two groups. In their respective charts, the age corresponding to the baby is found in the first column on the left, and then the height range of the baby is found horizontally.
"Median" stands for standard. Between -2SD and +2SD, it is also within the normal range, but parents should not be careless. If the height is less than -2SD, it is short; If it is greater than +2SD, it means that the baby is growing too fast.
In other words, half of our children have not reached the average level. Even if the parents are excellent in height, more than half of the children do not reach the height expected by heredity.
The height of a child will really directly affect his future image, and it will also be related to all aspects of his life. Therefore, for parents, the child's size will always touch our heartstrings.
What determines the height of that baby and what factors affect it?
Sun Nianxun, a obstetrician at Peking Union Medical College Hospital, believes that 75% of a child's height depends on heredity, and the remaining 25% is determined by the environment.
Heredity:
There is no doubt that a person's height is first influenced by his parents' heredity. If both parents are not tall, there is a great chance that the child will not grow too tall. If both parents are tall, the child is born with the potential to grow tall. But if only one of my parents is taller, what do you think?
Dr. Sun Nianxun gave such a calculation formula, which can predict how tall our children will grow in the future:
(Formula suggested collection yo ~)
For example, if the father 180cm and the mother 160cm, then the son will probably be (180+160)1.082 =183.6cm in the future. The daughter may be (1800.923+160) 2 =163 cm.
It can be seen that the height of a child is not decided by one party, but by both parents. This calculation method is to calculate the height that the child is likely to inherit. However, this is not absolute. Because the environment will also play a very important role in the growth of children.
Environment:
The height of a child will be influenced by the acquired environment, such as calcium. Children's bone growth is inseparable from calcium. If the baby is in a rapid development stage and the calcium supply is insufficient, then bone growth is difficult to keep up with the rhythm.
The other is nutrition. The baby's growth and development can't be separated from the interaction of major nutrients. Insufficient nutrition will directly lead to the baby's growth retardation. Overnutrition may cause precocious puberty, which will lead to early closure of the epiphyseal line.
Cui Yutao, a pediatrician, thinks that once the epiphyseal lines at both ends of a long bone close and disappear, it means that the bone will not grow again.
Another is the secretion of growth hormone. Only when the growth hormone secretion is normal, the baby will grow and develop healthily.
Therefore, apart from parents' inheritance, we should also pay special attention to the influence of environmental factors on our baby. Try to grasp this 25% chance, and strive for a few centimeters more for the baby's height on the basis of congenital.
To make children become "acquired players" on the basis of heredity, we need our parents to pay more attention to the following aspects at ordinary times:
1, balanced nutrition
As soon as the baby is born, it is best to breastfeed until half a year or a year. Conditional, even can be fed for 2 years. The nutrition contained in breast milk is enough for the baby's development before half a year old. After 6 months, we should pay attention to timely supplement of iron. Complementary food should also be from fine to coarse, from single to multiple types.
But don't save enough energy to make up for the baby as soon as you hear what to say, so as not to cause precocious puberty. Although nutritional supplement is important, balanced and reasonable is a healthy eating habit.
2. Exercise properly
Scientific exercise can not only accelerate metabolism, but also stimulate the secretion of growth hormone, so as to maximize the genetic potential.
Younger babies, don't just hold them, you should let them move properly. For example, within one year old, we can combine the growth law and let them practice raising their heads, turning over and climbing. When you can walk, you can take your baby out for a walk every day and encourage them to take more legs.
Older children can try all kinds of safe outdoor sports and games. Two hours of outdoor activities every day can expose you to ultraviolet rays in the sun, which can help the synthesis of vitamin D and thus promote bone growth.
3. Ensure adequate sleep
High quality sleep can better promote the secretion of growth hormone. American parenting expert Dr. Sears believes that:
If the baby's corresponding sleep time is not so long, parents should not worry. If the baby sleeps well at night, is energetic during the day and is in a good emotional state, it means that there is no problem with his sleep time. On the contrary, if the child always wakes up at night, the quality of sleep may not be high, and parents should help the baby correct it in time.
4. Grasp the critical period of growth and height.
Children in infancy and adolescence are two key periods for growing up. During this period, children's heads tend to obviously go up. Parents should pay more attention to the above points in these two periods.
