The increase in body length is considered one of the most important indicators of child development. The growth of a child by age changes according to established patterns that are inherent in certain time intervals. An important role in the process under consideration is played by heredity. In addition, scientists have proven that a growing body is greatly influenced by external factors, such as the quality of nutrition. To understand the correctness of growth indicators, you need to consider the established age norms, taking into account the genetic data of the child and the conditions of his life.

Conventionally, the development of a child is divided into four main time periods: infants - from birth to one year, early period - from 12 to 36 months, preschoolers - from 3 to 7 years, and adolescents - 7-17 years.

Baby

The most intense changes in babies occur from the first day to a year. In this time interval, the growth of the child by age is classified according to monthly indicators. Every month, mom visits the pediatrician to control the growing body of the crumbs. Specialistevaluates the measurement results in accordance with the tables developed by WHO, taking into account the heredity of the baby.

Until 2006, old growth tables were used, the data in which were somewhat overestimated, as they were focused on babies receiving artificial feeding. Today, WHO takes into account infants and looks at their development indicators in a different way. Since 2006, the organization has provided new data that determines the height of children by age. The table below will help you figure out how your baby is growing.

Height	Gender	Age, months
		12	11	10	9	8	7	6	5	4	3	2	1	0
Low - Below average	Boy	71-73	70-72	69-71	68-70	66-68	65-67	63-66	62-64	60-62	57-59	54-56	51-53	46-48
	Girl	69-71	68	67-69	65-68	64-66	63-65	61-64	60-62	58-60	56-58	53-55	50-52	45-47
Medium	Boy	76	75	73	72	71	69	68	66	64	61	58	55	50
	Girl	74	73	72	70	69	67	66	64	62	60	57	54	49
Above Average - Tall	Boy	78-81	77-79	76-78	74-77	73-75	71-74	70-72	68-70	66-68	64-66	60-62	57-59	52-54
	Girl	77-79	75-78	74-76	73-75	71-74	70-72	68-70	66-69	64-66	62-64	59-61	56-58	51-53

Growth values in the range from "Below average" to "Above average" correspond to normal growth. The numbers in the "Low" and "High" sections may indicate both the genetic characteristics of the child and hormonal disorders. You should pay attention to this and consult a pediatrician. Growth that is less than the "Low" limit and more than the "High" interval most often indicates certain diseases associated with a violation of the process of physical development. Such babies require an assessment of their condition by specialists, since these pathologies need to be corrected.

Early period

After a year, the baby continues to grow, but not as intensively as in the previous period. From one year to three years of age, you can put the baby to the height meter once every 6 months.

For this period, WHO has also established indicators that can be used to estimate the growth of children by age. The table below contains average standards.

Age	3 years	2, 5 years	2 years	1, 5 years	1 year
Boys	92 to 100	89 to 94	84 to 89	From 79 to 84	From 74 to 77
Girls	From 93 to 98	88 to 92	83 to 88	From 79 to 82	From 73 to 76

Preschool

It is customary to classify children from three to seven years of age as preschoolers. They grow and improve in development. After three years, the growth of the child by age is characterized by unevenness. Between 4 and 5 years, babies grow by about four to six centimeters. But in the sixth and seventh years, the growth rate increases, and the annual increase on average ranges from 8 to 10 cm. Six-year-olds and seven-year-olds have a stretching stage. At this age, both lower and upper limbs lengthen in children.

Teenagers

If the length of the body of babies approximately coincides with the tabular data, then in adolescence, the growth of the child by age is difficult to subordinate to certain intervals. Children at this stage grow up in leaps and bounds. And each of them may have a jump in a different period.

One child may already reach their final height at 13 years old, while another only begins to stretch at this time. At the same time, a certain teenager can grow up in one summer, while hisfriend adds in growth gradually. Children stretch most intensively with the onset of puberty. Girls begin to grow earlier and faster - at 10-12 years old, and boys - at 13-16 years old.

What determines the growth process?

For each parent, it is important to correctly match the height and age of the child. Therefore, you need to know that the process of growing up is influenced by various factors. The main role belongs to heredity. Proper nutrition is also important. A balanced diet is a prerequisite for the proper formation of children. Providing their child with the necessary amount of fat, protein and carbohydrate components, as well as mineral s alts and vitamin elements, parents create conditions for the proper development, growth and formation of his body in all time intervals. These include infants, early childhood, preschool and adolescence.

The weight and height of a child also depend on many other factors: physical exercises, the quality of care for him, the daily routine, the psychological atmosphere in the family.

A child who gets enough rest develops properly, but lack of sleep and chronic fatigue can negatively affect physical performance. In addition, there is an opinion of scientists that children increase their growth more intensively during sleep.

Basketball, jumping, volleyball and other sports activities have a stimulating effect on the young body. But constant stress and mental stress negatively affect not only growth, but also he alth in general.
