The baby's chin is shaking

Quite often, parents face such a phenomenon, when their babies, for some unknown reason, shake their chins. The first thought that visits the head of a young mother is the presence of pathology, which is why this phenomenon is observed. However, this is not the case.

Why does the baby shake his chin?

The main reason that explains why a baby's chin is shaking is the immaturity of his nervous system, which consists in the instability of the work of the nerve centers. This reason has a so-called neurological nature. However, they also provide a hormonal cause. It is based on the immaturity of the adrenal medulla, which causes them to throw a large amount of the hormone norepinephrine into the baby's blood. That is why the child often shakes his chin.

A separate case is when the baby is crying and his chin is shaking. At this time, there is an ordinary muscle twitching, which is a consequence of the overstrain of mimic muscles. At the moment when the baby overgrows to cry, the tremor immediately disappears.

In addition to the above reasons, which explain why the baby has a shaking chin, there are others, the main one of which is stress. No matter how strange it seems, but for a newborn, almost all the manipulations that mom does with him every day (feeding, bathing) are accompanied by stress, and also:

• loud noise;
• bright lighting;
• fast, sharp movement;
• a feeling of hunger and thirst.

Any phenomenon of this kind can lead to the fact that the child begins to shake his chin.

When there are reasons for concern?

There is nothing terrible in the fact that your child sometimes shakes his chin. Up to 3 months, tremor of the lower jaw is observed in almost 60% of babies. If the age of the baby is already approaching 6 months, and the tremor is not disappears, it is necessary to think and will address to the neuropathologist.

Most often, with pathology, the presence of tremors is not related to the restless state of the crumbs; his chin is shaking when the baby is calm. In addition, in the presence of the disease, not only the muscles located on the lower jaw, but also the muscles of the head are involved in the tremor. However, quite often the skin in the nasolabial triangle begins to acquire a bluish tinge. All these signs indicate a possible presence of a neurological disease, for the diagnosis of which it is necessary to consult a doctor.
