Many parents are very worried when they realize that their children are shorter than their peers. In fact, the growth of height in children is influenced by many factors.
The height of a child develops from in the womb to adulthood. However, there are two “golden” stages for a child to develop, which parents need to understand in order to help their child develop most strongly.
How to measure a child’s height?
In order to judge the true height of a child, it is necessary to compare it with most normal children of the same race, age and sex.
In general, the rules of growth and development of children before the age of 3 years are roughly as follows: (The following is the average growth rate of height, not forced to compare, just for reference)
– 0-3 months: 3.5cm/month
– 4-6 months: 2cm/month
– 7-9 months: 1.5 cm/month
– 10-12 months: 1cm/month
– Age 1-2 years: 10-11cm/month
– 2 years: 4-7cm/month
The height of the child is always a concern of many parents.
Babies can grow up to 25cm in the first year after birth, 10-12cm in the second year, and an average of about 8cm in the third year, and generally grow 5-6cm/year from 3 years of age until birth. , if less than 5 cm / year, it should be noted, adolescence is about 7-12 cm / year.
Regarding the use of the annual growth index to assess the baby’s height, many parents are worried whether this method is timely, if the child’s height is short, will it slow down the child’s height growth?
The annual growth record can not only speak to the standard of height but can also record well the changes in the height of the child. Therefore, parents should pay attention to monitor and record the child’s growth and development process, to get the most accurate comparison.
Two golden stages for children to grow up, parents must know how to understand
In fact, the height of a child is not completely determined by genetics. In the process of height development, there are two “golden periods”, namely before the age of 2 years and puberty.
First 1000 days of life
The first 1000 days of life are counted from the time the baby is conceived to the age of 24 months. This is a golden period of height and physical development and has been recommended by the World Health Organization.
In the first year, a child can grow from 25 cm, and the next 2 years increase by 10 cm per year. The first 1000 days of life are the period that determines 60% of the child’s ability to grow in height in the future.
After the age of 2 years, the child’s growth rate will decrease and only increase by about 6.2 cm per year, bone density also increases by about 1% per year.
However, if at this stage the child gets the right nutrition to support the growth of his height, it will be the basis for the child to develop properly during puberty.
The first 1000 days of life are counted from the time the baby is conceived to the age of 24 months. This is the golden period of height growth.
Puberty is counted from the age of 10 to 15 years, this is a period marked by tremendous growth in both muscle and skeleton and sexual function.
The growth rate and height are very fast, which can increase from 10 cm per year in girls at the age of 10 years and gradually increase to 15 cm per year at the age of 12 years.
For boys, the growth rate is 10 cm per year at the age of 12 years and reaches a maximum of 15 cm per year until the age of 14 years. Then the growth rate will decrease gradually at the age of 15 years in girls and 17 years in boys.
Puberty determines 23% of the average adult height. Bone size and bone mass and mineral density in each bone increase by about 4% per year from age 8 through adolescence.
Height and growth are associated with rapid accumulation of bone mass and possibly growth hormone activity. Therefore, it is very necessary for parents to pay attention to supplementation with appropriate nutrition and exercise patterns for children of this age.
Boys and girls will differ in height during development.
So what should parents do to help their child develop an effective height in the golden age?
Feeding children the right way
Before a baby enters the weaning stage, ensuring a daily supply of milk is essential for growth and development. Before the age of 1 year, the daily milk intake should be 600-800 ml, and after the age of 1 year, the daily milk intake should be 300-500 ml.
After the child has eaten solid foods, priority should be given to iron-rich red meat and animal organs, calcium-rich vegetables, and zinc-rich seafood.
In addition to ensuring complete nutrition, parents should also pay attention to vitamin D supplements for children. Vitamin D more than 400IU per day can increase calcium absorption and strengthen your baby’s bone growth.
Nutrition is one of the important factors to help children increase their height effectively.
Let the children play well
Proper exercise can increase the secretion of growth hormone well, according to many data, regular exercise and exercise can improve the body’s blood circulation, increase the absorption of nutrients by the body, and increase the growth ability of bone cells.
Surveys and studies by health professionals show that children who regularly participate in sports are on average 4 to 8 cm taller than children of the same age who do not participate in sports.
Children aged 1 to 3 years need to ensure at least 1 hour of outdoor activities a day, after 3 years need to ensure at least 2 hours a day.
If outdoor activities are not possible due to weather constraints, try to design some indoor games so that the children can be fully active.
The World Health Organization recommends that children and adolescents ages 5 to 17 exercise at least 3 times a week, and each exercise requires at least 1 hour of moderate to vigorous physical activity.
Children with proper exercise or movement can increase the secretion of growth hormone.
Let the children sleep well
The secretion of growth hormone in the body also needs to be done regularly. During the day, the amount of growth hormone secreted is relatively low, from 1 to 2 hours after the child falls asleep is the peak period of growth hormone secretion, the amount of secretion is about 3 times higher than during the day.
Therefore, parents should ensure that the tar gets enough sleep at night, the body will naturally secrete sufficient growth hormone after sleep, helping the child grow taller.
In general, babies need only 14 to 20 hours of sleep per day, 12 to 14 hours for 1 to 3 year olds, and 11 to 12 hours for 4 to 6 year olds.
