The growth of a child at 3 years old depends on how intensively the baby develops. A 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:

- child's nutrition (how much he gets proteins, fats, carbohydrates, vitamins and other essential trace elements);

-heredity;

- hormonal background.

Also, the growth of a child at 3 years old is influenced by factors such as good care, physical activity, long sleep, a favorable psychological atmosphere surrounding the child.

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

In addition, the growth of a child at the age of 3 increases intensively during sleep, especially in the morning (when the child constantly does not get enough sleep or gets up early, this negatively affects his development).

Psychological factors of growth slowdown

A huge impact on the physical development of children 3 years oldhas a gender. Boys grow faster than girls. The 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 adolescents have a large amount of sex hormones in their bodies, growth slows down (by the age of 18 it practically stops).

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

Measurement rules

In order to measure the height of a child under 3 years old, a measuring tape is used. This procedure is done on the table. The tape is pre-straightened and well fixed.

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

Then, pressing a little on the knees, straighten the legs and measure.

To measure the height of a child at 3 years old, you can use a height meter (this is a centimeter tape made of paper). The child is taken off his shoes and put on the floor, while leaning his back against the ruler. The body should be straightened, the arms should be lowered along the body, the knees should be extended, and the feet should be shifted. During the measurement, you need to ensure that the child easily comes into contact with the wall in three places: the back (shoulder blades), booty and heels. We put any flat object perpendicular to the stadiometer on his head and make a mark on the scale, by which we can easily recognize the height of the child. The table of standards allows you to judge the correct development of the child.

Determination of weight

Weight can be easily read using a digital scale. It is necessary to control that the child is located strictly in the center of the measuring device. The method of measurement depends on age. Babies are put on a diaper, after weighing, its weight is subtracted from the total indicator.

Weigh in the morning, before feeding, after the baby has gone to the toilet.

The circumference of the chest is measured mainly with a centimeter tape, it is placed on the chest under the shoulder blades, the child should take the arms to the side. Then he should 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 freeze. For girls with well-developed breasts, the tape is applied over the chest and measured.

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

Assessment of anthropometric indicators using centile tables

The centile table is used to determine the degree of development of the baby, it subdivides children according to the parameters of height, weight, head and chest circumference. Using such tables is quite simple and convenient, and the results are easy to understand.

The columns of the tables show us the numerical boundaries of the characteristics by the proportion (percentage, centile) of children of a certain age and gender.

For the average values or normal values take the values that have halfhe althy children, this corresponds to an interval of 25-50-75%. The table, which contains indicators such as age, weight, height of babies, indicates these indicators, marking them in red.

Intervals located near the average values are evaluated below or above the average (10-25% and 75-90%). Parents can evaluate such indicators as quite normal.

But when the indicator is in the zone of 3-10 or 90-97%, you should be alert and see a doctor. When the baby's indicators are located in this zone, it is necessary to conduct an examination of the baby.

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

To help you understand what a centile scale is, let's take an example. We have one hundred babies of the same age and gender. They are in order of increasing height, starting with the smallest and ending with the largest. Growththe smallest of the first three babies, he is considered very low. From 3 to 10 - low, from 10 to 25 - below average, from 25 to 75 - average, from 75 to 90 is already considered above average, from 90 to 97, according to existing standards, is considered high and the last three babies are very tall.

Conclusion

When a child lived for 3 years, his height and weight should correspond to the normal indicators of the anthropological table. This once again confirms the fact that he develops normally, receives proper care, observes the daily routine and eats fully.

For the good development of the child, he must be taught to sports, work at an early age. The conclusion suggests itself: so that the child does not lag behind in growth, you need to ensure that he observes the daily routine, eats right and is friends with physical education. As a result, physiological development will not be long in coming.
