Growth of a child in 3 years. Table: age, weight, height of the child

The growth of a child in 3 years depends on how intensively the baby develops. The constant increase in the growth parameter is a pretty good indicator of development.

Anthropological factors and their impact on child development

The following factors influence the physiological development of children:

- baby nutrition (in what quantities does he get proteins, fats, carbohydrates, vitamins and other necessary trace elements);

- heredity;

- hormonal background.

Also, factors such as good care, physical activity, prolonged sleep, favorable psychological atmosphere surrounding the child, influence the growth of a child at 3 years.

In the process of growing up, the physical development of children is positively influenced by sport, which is accompanied by frequent jumps (volleyball, basketball).

In addition, the growth of the child at 3 years intensively increases during sleep, especially in the morning (when the child does not get enough sleep or gets up early, it negatively affects its development).

Psychological factors of growth retardation

A huge influence on the physical development of children 3 years old has sex. Boys grow faster than girls. An exception is adolescence, it is then that girls often overtake boys in development, but then the boys still gain their own.

Puberty also plays an important role. When there is a large amount of sex hormones in the body of adolescents, growth slows down (by the age of 18, it practically stops).

On the growth of a child 3 years of age can also affect the climatic conditions.

Measurement rules

In order to measure the growth of a child under 3 years of age, a measuring tape is used. This procedure is done on the table. Preliminary, the ribbon is straightened and fastened well.

The baby is placed on a flat surface so that the top of the head lies on the beginning of the measuring tape.

Then, a little pressing on your knees, straighten your legs and make a stop.

To measure the growth of a child in 3 years, you can use a rostomer (this is a centimeter tape of paper). The child is undressed and put on the floor, with his back to the ruler. The body should be straightened, the hands should be lowered along the trunk, the knees should be unbent, and the feet - shifted. During the measurement, you need to ensure that the child easily touched the wall in three places: back (spatula), booty and heels. On his head we put perpendicularly to the growth meter any flat object and on the scale make a mark on which we easily learn the growth of the child. The table of norms allows to judge the correct development of the child.

Weight Determination

Weight can be easily recognized using digital scales. It is necessary to supervise, that the child settled down strictly on the center of the measuring device. The method of measurement depends on age. Toddlers put on a diaper, after weighing out the total figure subtract her weight.

Weigh in the morning, before feeding, after the child went to the toilet.

The circumference of the breast is measured mainly by a centimeter tape, it is placed on the chest under the shoulder blades, the child should take his hands aside. Then he must lower his hands, and the ends of the measuring tape are connected at the level of the nipples. At the moment when the child breathes evenly, they stop. Girls with well developed breasts are banded over the chest and measured.

When measuring the circumference of the head, the tape for measurement is placed behind the back of the head, and in front - on the superciliary arches. The ends of the tape are connected and the result of the measurement is obtained.

Estimation of anthropometric indicators using centile tables

The centenary table is used to determine the degree of development of the baby, it divides children according to the parameters of growth, weight, head circumference and chest. To use such tables is quite simple and convenient, it's easy to understand the results.

The columns of the tables show us the numerical boundaries of the signs according to the percentage (percentage, centile) of children of a certain age and sex.

Mean values or normal values are taken from the values that have half of the healthy children, this corresponds to an interval of 25-50-75%. A table that contains indicators such as age, weight, height of toddlers, points to these indicators, indicating them in red.

The intervals next to the average values are estimated below or above the average (10-25% and 75-90%). Such indicators parents can estimate as quite normal.

But when the indicator is located in the zone of 3-10 or 90-97%, it is worthwhile to get worried and consult a doctor. When the indicators of the baby are located in this area, it is necessary to conduct a survey of the baby.

When the child's indicators went beyond the established limits of the norm, namely for the values of 3 or 97%, most likely, he has some sort of pathology that affects his physical development. When you have such values, only a doctor can determine the reason for the developmental gap in the child's development and help to solve this problem.

To help you understand what the centile scale is, let's give an example. We have one hundred kids of the same age and gender. They stand on increasing growth, from small to large. The growth of the first three kids is the smallest, it is considered very low. From 3 to 10 - low, 10 to 25 - below average, from 25 to 75 - medium, from 75 to 90 it is already above the average, from 90 to 97, according to the existing standards, it is considered high and the last three kids with very high growth .

Conclusion

When the child lived for 3 years, the height and weight of it should correspond to the normal indices of the anthropological table. This once again confirms the fact that he is developing normally, receives proper care, observes the regime of the day and fully eats.

For a good development of the child it must be accustomed to sports, work at an early age. The conclusion suggests itself: that the child does not lag behind in growth, it is necessary to watch that he observed the regime of the day, eat properly and be friends with physical education. As a result, physiological development will not take long.
