The shaking chin of a newborn in official medicine is called the word "tremor" - this term refers to all muscle contractions that occur involuntarily. In general, this symptom is considered quite common among infants - it indicates an incompletely formed nervous and endocrine systems. In addition, the baby's chin can often tremble during strong emotional arousal, for example, after crying. Usually this manifestation is accompanied by unconscious twitching of the hands.
Possible causes
You will not notice a shaking chin in a newborn when the baby is in a calm state. However, if he is in pain, scared, hungry or dissatisfied with something, the tremor is evident. The reason for this phenomenon is that the baby's nervous system develops quite gradually. In particular, the nerve centers responsible for the coordination of movements are activated from birth to three to four months. Surely you paid attention to the fact that small children cry somehow “especially” - with anguish, excitedly. This islooks frightening, but the explanation is quite simple: norepinephrine (a hormone produced by the endocrine glands) is not controlled by the center of the brain. When a baby becomes very excited, his entire nervous system reacts. Hence the muscle tone. Therefore, if the child's chin is shaking after crying, watch him: if, as the baby calms down, the tic stops, you have no reason to worry. However, if hypertonicity is observed, be sure to see a pediatrician.
Predisposition
As a rule, such a problem as a shaking chin in a newborn disappears without a trace by three months. However, why is the nervous system of some children constantly excited, while others react sluggishly to stimuli? Pediatricians argue that the type of temperament plays an important role: it turns out that already in infancy it is possible to determine what character the little man is endowed with and who he will be in adulthood: an apathetic phlegmatic, a sad melancholic or a quick-tempered choleric.
Developmental Deviations
Do not forget that in some cases, a shaking chin in a newborn is considered a symptom that the baby is not developing fast enough. Associated signs to look out for are restless sleep and twitching of the entire head. For prevention, doctors advise bathing the baby in warm baths with chamomile and valerian, as well as giving him a special massage.
Background
There are a number of prerequisites for the development of tremor. For example, if a month-old baby has a chin shaking, it is likely that he was born prematurely. It is no coincidence that pregnant women are advised not to be nervous, to avoid any stress - this can also become a provoking factor, since the mother's experiences are transmitted to the fetus. Difficult childbirth associated with hypoxia (for example, if the fetus is wrapped around the umbilical cord) negatively affects brain function, which is also considered one of the causes of tremor development.
Treatment
Of course, it is best to consult a pediatric neurologist about tremor. However, if for some reason you do not have such an opportunity, use folk remedies. Great help, for example, a light massage of the whole body using oil, as well as daily bathing in warm water.
