How to tell if your baby’s height is slow?
Whether or not your height is satisfactory depends on several factors. The first is the genetic factor, which accounts for 70%. The transformation depends on other conditions, including exercise, nutrition, environmental and social factors.
In the first 3 months after birth, the average length is 3 months per month.
5 cm; 3-6 months after birth, with an average length of 2 per month.
0 cm; 6-12 months after birth, with an average monthly length of 1.
The baby was 25 centimeters long in the first year of birth, 10 centimeters in the second year, and 8 centimeters in the third year.
If your baby’s growth rate is less than 70% of the above value, you can judge it to grow slowly.
How to predict the baby’s height is affected by heredity. From the height of the parents, the height that the baby can reach in the future can be predicted to a certain extent.
[Boy]Future height (cm) = (father height + mother height) × 1.
078 ÷ 2[Girl]Future height (cm) = (Father height × 0.
923 + Mother height) ÷ 2 Tip: The influence of genetic factors on the baby’s height is not absolute, and the genetic heritability of height is 0.
72, which means that 72% of children’s height is genetically affected.
So what other factors will affect the growth of the child?
In fact, the final height is also affected by other acquired factors.
Effect of nutrition When the child’s nutrition can not meet the needs of bone growth, the growth rate of length will slow down.
Nutrients closely related to bone growth are vitamin D, calcium and phosphorus.
Insufficient iodine and zinc can also make children short.
There is no absolute long-height food. The most important thing is to ensure nutritional balance and ensure that the supplements are rich and comprehensive.
5 recommended foods that increase in height: milk, sardines, spinach, carrots, oranges.
Foods that are not good for growing tall are mainly less nutritious, which can increase the baby’s satiety and affect the baby’s intake of other foods. Some also consume calcium in the body and eventually lead to malnutrition.
The effect of sleep on growth hormone secreted by the pituitary gland is the most important hormone to promote children’s growth.
The secretion of human growth hormone is unbalanced within 24 hours a day. Only after falling asleep can the secreted growth hormone be secreted in the body.
Characteristics of auxin secretion: from childhood to prepuberty, strong secretion during sleep, the amount of auxin secreted from 9 pm to 9 am the next day is 3 times that of 12 hours during the day, especially 70 minutes after falling asleep at 9 pmA peak of secretion may occur.
Sleep time Generally, newborns require 20 hours of sleep every day and night, from 15 to 18 hours from February to June; from June to 18 from 13 to 15 hours; from 18 to 3 years and from 12 to 13 hours;11-12 hours.
The sleeping environment creates the best sleeping environment, the lights are dim, and the noise is eliminated.
In addition to the duration of sleep, the quality of sleep is also important.
The sleep time required by children every day, individual differences converge. If some children have reduced sleep time, but their mental, emotional, and growth development is normal, there is no need to force it.
Effects of exercise Before the sacral ribs stop growing, physical exercise is often performed to correct sacral cartilage hyperplasia; improve blood circulation, enhance nutrient absorption, and increase bone cell growth; mechanical forces can promote calcium precipitation in bones and make bones thickerAnd burden.
