For example, when I took Bubu for vaccination, I heard an old woman say, "My granddaughter's pants last year can still be worn this year, and they are not so long this year." The pants that were just right last year can still be worn this year, and the baby really doesn't grow fast. No wonder the old woman is worried.
However, every baby has its own growth rhythm. Being shorter than others doesn't mean being backward. So, what is the height and weight of the baby at different stages?
The Capital Institute of Pediatrics released the 2020 edition of the standard deviation unit numerical table of height and weight for children and adolescents aged 0- 18. Parents may wish to compare and see if their baby is within the standard range.
What do you think of these two pictures?
First, boys and girls are divided into two groups. In their respective charts, the first column on the left finds the corresponding age of the baby, and then horizontally finds the height range of the baby.
"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 are not up to the average. Even if the parents are excellent in height, more than half of the children can't reach the height expected by heredity.
The height of a child will really directly affect his future image, and it will also affect all aspects of his life. Therefore, for parents, the size of children will always touch our heartstrings.
What determines the baby's height and what factors affect it?
Sun Nianxun, an 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' inheritance. If both parents are not tall, there is a great chance that the child will not grow tall. If both parents are tall, children are born with high potential. But what do you think if my parents are the only ones tall?
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 is 180cm and the mother is 160cm, then the son is likely to 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, it is difficult for the bone growth to keep up with the rhythm.
The other is nutrition. The baby's growth and development are inseparable from the interaction of major nutrients. Insufficient nutrition will directly lead to the baby's growth retardation. Overnutrition may lead to precocious puberty, which in turn leads to premature closure of epiphysis.
Cui Yutao, a pediatrician, believes that once the epiphyseal lines at both ends of a long bone are closed and disappear, it means that the bone will not grow back.
The other is the secretion of growth hormone. Only when the growth hormone secretion is normal can the baby grow and develop healthily.
Therefore, in addition to parental inheritance, special attention should be paid to the influence of environmental factors on the 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, our parents need to pay more attention to the following aspects in peacetime:
1, balanced nutrition
As soon as the baby is born, it is best to breastfeed for half a year or a year. Conditional, you can even feed it 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.
But don't save enough energy to make up for your 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.
Step 2 Exercise properly
Scientific exercise can not only accelerate metabolism, but also stimulate the secretion of growth hormone, thus maximizing the genetic potential.
Younger babies, don't just hold them, let them move properly. For example, within one year old, they can practice raising their heads, turning over and climbing according to the growth law. When you can walk, you can take your baby out for a walk every day and encourage them to walk more.
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 helps to synthesize vitamin D, thus promoting bone growth.
Step 3 get enough 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 that long, parents don't have to worry. If the baby sleeps well at night, is energetic during the day and is in a good mood, it means that his sleep time is no problem. On the contrary, if the child is always awake at night, the quality of sleep may not be high, and parents should help the baby to correct it in time.
4. Grasp the critical period of growth and height.
Childhood and adolescence are two key periods for children's growth. During this period, the child's head tends to be obviously upward. Parents should pay more attention to the above points in these two periods.
