In the first six months of life, the baby develops many new skills: keeps her head well, turns over, and crawls actively. The most mobile kids try to lift the body, clutching at the back of the bed or mother’s hand. Consider when the child begins to sit on his own, and what to do if this does not happen within the time limits set by pediatricians.
Stages of physical development
The development of the musculoskeletal system of the newborn occurs in several stages. The spine, initially representing an absolutely straight line, gradually acquires natural curves. At about 3-4 months, when the baby begins to keep his head well in the prone position, a cervical lordosis is formed – the bend of the upper vertebrae forward. By half a year, as a result of high motor activity and attempts to translate the upper part of the body into a vertical position, the middle part of the chest under the action of gravity slightly bends back. At this stage of development, the spine is able to withstand increasing loads and is ready to start sitting down. In accordance with the average pediatric norms, the child should:
- at 6 months, sit down with support;
- at 7 months for some time to sit without support;
- at 8 months, without the help of an adult, sit down from a prone position or stand on all fours.
Some babies may start learning a new skill a few weeks earlier or later than the expected time. It depends not only on the state of health, but also on the weight, body, temperament and other individual characteristics. Therefore, the question of how many months the child begins to sit independently, pediatricians can not give a definite answer.
Is it possible to sit the child on purpose?
Many parents rush to events, sitting infants much earlier than expected. It is strictly forbidden to do this, since early verticalization leads to the development of a number of serious complications, including limb deformities, severe posture disorders, and pathologies of the genitourinary system. For this reason, you should not persevere until you are 6 months old. Scarce is ready to sit down if he:
- rolls well from back to stomach and in the opposite direction, confidently holding the head and upper body vertically;
- crawls on all fours and pulls up on his hands, grasping the fixed support or the fingers of an adult;
- shows a desire to change the usual position.
To determine the physiological readiness of the baby to master a new skill, orthopedists advise him to sit on a solid surface for a few seconds, slightly supporting him by the flank or back. In the future, you can sit down without fear, if:
- the baby sits confidently, trying to maintain balance, and does not fall on its side;
- the body is tilted forward, resting on arms extended in front of you;
- legs apart and slightly turned out socks out;
- the back is straight, the spine slightly flexes in the cervical, thoracic and lumbar regions;
- the chin is lowered, but the head is well kept upright.
If at least one of the listed conditions is not fulfilled, occupations should be postponed, paying particular attention to the physical development and strengthening of the muscular system.
What to do when the child starts to sit too early? Pediatricians recommend unostentatiously suppress attempts to sit down, switching the attention of the crumbs to another interesting activity: playing, reading, walking. Active infants should be placed in the center of the crib or playpen, so that they could not grasp the sides or other support with their hands.
Stages of sitting down
If the kid is ready to learn a new skill, you should start sitting down by following these guidelines:
- It is necessary to conduct exercises daily, starting from 15-20 seconds in one set and gradually increasing the time of classes.
- The first sitting down is best carried out on the knees of an adult, turning the crumb back to his stomach. When he learns to keep his balance, he must move to a hard surface (floor, hard sofa or changing table). It is allowed to seat the baby from standing on all fours, lightly holding the shoulders or back so that it does not roll on its side.
- At the same time, in order to better adapt the spine to increasing loads, it is necessary to install the backrest of the car seat, the stroller and the highchair at an angle of 45 °. When the crumb learns to sit on its own, it can be placed in any of these devices with a straight back.
- During classes, it is prohibited to use a support in the form of a pillow or a rolled-up blanket, leave the baby for a long time sitting, and also put him in a walker or other devices to be forced to stand upright.
- Exercise is not recommended immediately after feeding or sleeping, during illness or feeling unwell. You should not force the baby to sit down, if he is not set up for classes, is naughty or passionate about the game.
What if the crumb is in no hurry to sit down?
If the baby does not sit on its own at 8-9 months and does not make any attempts to change its usual body position, it is necessary to contact a pediatrician, neurologist or orthopedist to rule out possible health problems. Often the delay in physical development is a consequence of birth trauma, fetal hypoxia, pathologies of the course of pregnancy, and intracranial pressure. Even in the absence of obvious violations, such children are shown a special massage, swimming, and physiotherapy according to indications.
To strengthen the spine and back muscles at home it is recommended:
- encourage any physical activity;
- more often wear the baby in her arms in an upright position;
- hang over the crib and scatter toys and bright objects around the room, stimulating the desire to reach out to them;
- do an intensive massage of the feet and legs;
- conduct physical exercises in a game form while reading, swimming or walking.
In the ideal case, the skill of sitting is acquired after mastering the crawling. Therefore, to help the baby to sit on its own, first of all it is necessary to teach him to crawl correctly.
Exercises for the back muscles
In order to help their child to master a new skill, doctors advise daily to exercise, strengthen the muscular corset and stimulate the development of a new skill:
- To stretch the hands of the baby, lying on his back on a hard surface (preferably on the floor or changing table), allowing him to hold his thumbs. Clutching the wrists of the crumbs, gently pull his hands up to the head and body were at a slight angle to the floor. It is not allowed to perform the exercise if the child’s head is thrown back. Hold for 15-20 seconds, then slowly return the crumbs to their original position. Make a few approaches with a small interval. After 2-3 weeks of classes, the child will try to sit down without the help of an adult.
- Raise the crumb lying on his stomach, holding him under the breast and knees. The legs should rest on the adult’s chest, shoulders and hips are stretched, the arms are extended forward. Hold in this position for 15-20 seconds.
- Pull up the baby on the back alternately by the left and right hand, helping to make active coups on the stomach and back.
- Put the baby belly on the gym ball and make circular springy movements and swaying in different directions. The upper part of the body should be slightly raised, resting on outstretched arms.
Do not stop classes when the child begins to sit on their own. In the future, gymnastics will help him get on his feet faster and take the first steps.
Difference between the sexes
More on the topic:
For a long time, there was a misconception among parents that boys start sitting earlier than girls. In fact, physical activity and the desire to learn new skills do not depend on gender. However, early sitting is the greatest danger to the body of future women, leading to disruption of the development of the pelvic organs. Therefore, when practicing with girls, care should be taken not to overload the spine.
