Whether the height can be as high as desired depends on several factors, first of all, genetic factors, which account for 70%, in addition, depends on other conditions, including exercise, nutrition, environmental and social factors, etc. In the first 3 months of life, the average monthly growth is 3.5 cm; from 3-6 months of life, the average monthly growth is 2.0 cm; from 6-12 months of life, the average monthly growth is 1.0-1.5 cm. The average baby grows a total of 25 cm in the first year of life, 10 cm in the second year, and 8 cm in the third year. If your baby’s growth rate is less than 70% of the above values, then it can be judged as slow growing. How to predict? Your baby’s height is strongly influenced by heredity, and you can predict your baby’s future height to a certain extent from the height of your parents.
Boy] Future height (cm) = (father’s height + mother’s height) × 1.078 ÷ 2 [Girl] Future height (cm) = (father’s height × 0.923 + mother’s height) ÷ 2
Tip: The influence of genetic factors on the baby’s height is not absolute, the heritability of height in genetics is 0.72, meaning that 72% of the child’s height is influenced by genetics. So what other factors will affect the child’s height? In fact, the final height is also influenced by other acquired factors. The influence of nutrition When a child’s nutrition does not meet the needs of bone growth, the rate of growth will be slowed down. Nutrients that are closely related to bone growth are vitamin D, calcium and phosphorus. Insufficient iodine and zinc can also cause children to be short.
There is no absolute food to grow taller. The most important thing is to ensure a balanced nutrition and to make sure that the intake of nutrients is adequate and comprehensive. 5 kinds of height-enhancing foods are especially recommended: milk, sardines, spinach, carrots, and oranges. Unfavorable growth foods
Mainly less nutrition, but can increase the baby’s satiety, affecting the baby’s intake of other foods, some also consume calcium in the body, eventually leading to malnutrition. The effect of sleep
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 during 24 hours a day, and only after a good sleep can the body secrete more growth hormone.
The amount of growth hormone secreted from 9 pm to 9 am is three times more than that secreted during the 12 hours of daytime, especially in the 70 minutes after going to sleep at 9 pm, a peak of secretion can occur.
Sleep time
Generally, newborns require 20 hours of sleep per day and night, from 2-6 months, 15-18 hours; from 6-18 months, 13-15 hours; from 18 months-3 years, 12-13 hours; from 3 years-7 years, 11-12 hours. Sleeping environment
Create the best sleep environment with dim lighting and eliminate noise. In addition to the amount of time spent sleeping, the quality of sleep is also important. The amount of sleep a child needs each day varies greatly among individuals. If some children sleep less, but have normal mental, emotional and growth development, there is no need to force them to do so.
Effects of exercise
Before epiphyseal cartilage stops proliferating, frequent physical exercise helps stimulate epiphyseal cartilage proliferation; improves blood circulation, enhances absorption of nutrients and improves bone cell growth; mechanical force promotes calcium precipitation in bone, making bones thick and solid.
