The picture below is the official standard for the growth and development of children under 7 years old.

Many treasure moms don't understand what kind of standard is normal, and it is normal height range between -2SD and +2SD. If the child's height is less than -2SD, it proves that the child's height is higher than that of children of the same age, if it is greater than +2SD, it proves that the child's height is higher among peers.

Parents should be reminded that not only should they pay attention to their children's height, but also their growth speed is very important. For babies between 2 and 4 years old, it will grow by at least 5.5 cm every year.

For babies aged 4-6, the annual growth rate is at least 5.0 cm, and the height growth becomes slow from the age of 6. From the age of 6 to adolescence, boys grow at least 4 cm and girls grow at least 4.5 cm.

If your child's height standard is not up to standard, and the speed of height growth is too slow, then Bao Ma please find the answer from the following three reasons.

One third of a child's height is influenced by his parents' height, which is what we call heredity, so there are many formulas to calculate the child's height through his parents' height.

Among the acquired factors, nutrition is the most important factor that affects children's height. The height of children who entered school in the last century is obviously different from that of children who enter school now. It is because the living standard has improved and everyone's nutrition has kept up.

Insufficient nutrition will lead to the child's developmental delay. Before the child is two years old, milk powder or breast milk, as well as the addition of complementary food, cannot be less. If the child is overweight, it is overnourished and needs parents to control it.

There are still a small number of children who grow too slowly because of insufficient secretion of growth hormone. If children want to grow up, they need to secrete enough growth hormone in the pituitary gland. If children have thyroid dysfunction, they may lead to weak children.

No matter what the reason, if the child's height is not up to standard, please ask Bao Ma to take the child to see a doctor immediately, and the doctor will give professional advice and answers, so as not to delay the child's growth.

Although heredity plays a part in the influence of children's height, the efforts of the day after tomorrow can really help children have a relatively ideal height.

In fact, there are many people who have confirmed that exercise can help children grow taller, especially Xu Jinglei, who has personally said her experience of growing taller because she has been insisting on stretching.

Xu Jinglei was the shortest classmate in her class when she was in junior high school. In order to change her height, she insisted on stretching every day. By the second day of junior high school, she was the tallest lesbian in her class.

Under the condition of ensuring nutrition, scientific and reasonable exercise can help children balance the metabolism of calcium and phosphorus, accelerate the precipitation of minerals in the body, and stimulate the secretion of growth hormone, which can help children grow taller.

When the baby is two years old, Bao Ma can take the baby to outdoor sports. Sunbathing helps to produce vitamin D and can transport calcium. Getting in touch with some ball games and letting the baby run in nature is also good for the mood.

We all know that children need growth hormone for growth, but how does growth hormone come from? Growth hormone secreted by the brain is the most vigorous time when sleeping.

Generally, the secretion of growth hormone reaches its peak at 1 hour after the baby falls asleep, so regular sleep is more helpful for the baby to secrete growth hormone and make the baby have an ideal height.

Babies aged 0 to 3 months should sleep 14 to 17 hours a day, and babies aged 4 to 1 1 month should sleep 12 to 16 hours a day. 1 to 2 years old.

These are the things about the baby's height. Every baby is an independent individual. The standard mentioned above is an average standard, which is not suitable for all babies.

If you find that your baby doesn't meet the standard, you can take your child to the doctor for advice. In addition, many factors will affect the height of children, such as heredity, nutrition, exercise and sleep.

Nowadays, children are nutritionally adequate, that is, they don't have enough exercise and sleep, especially after their children go to school, which obviously leads to their unsatisfactory height.
