Why does chin tremor occur in newborns?
Tremor of the chin in newborns is a twitching of the muscles. As a rule, this is observed in children from birth. Up to three months, the "jitter" of the chin is not considered pathology.
The tremor of the child's chin is the consequencean underdeveloped nervous system that responds to the brain for movement. Also, the cause of "trembling" may be an excessive content of norepinephrine in the bloodstream of a child when manifesting certain emotions.
In the first year of life, the baby passes severalcritical periods of the development of the nervous system. It is then that the chin tremor in newborns is most likely. In these periods, the likelihood of a malfunction in normal development is greatest. During the first, third, ninth and twelfth months of a child's life, parents need to be especially careful. In these months, pediatricians strongly recommend visiting a neurologist. Usually, the tremor of the chin in newborns occurs when crying or after breastfeeding.
If at three months and older your baby still hasthere are bouts of "jitter" of the chin - this means that your baby's nervous system was damaged during pregnancy, and possibly during labor. The reason to find it is difficult, because even the stress of the future mother can be the reason. All that a woman experiences during pregnancy is experienced by a future child. The stress experienced by mother leads to disturbances in the central nervous system and in the endocrine system of the baby. Also, the cause of norepinephrine increase may be fetal hypoxia. In turn, there are many reasons for the lack of oxygen. This is a violation of the functions of the placenta, and bleeding, and the threat of miscarriage or intrauterine infection. Hypoxia can also occur during childbirth. The cause may serve as factors such as weakness of labor, cord injury and many other troubles. All of the above problems lead to a disruption of oxygen in the child's brain. As a consequence - tremor of the chin in a child, whose treatment is often not necessary, but require a systematic consultation with a neurologist.
Preterm infants often have not only"Trembling" of the chin, but of the limbs and lips. This is due to the immaturity of the central nervous system. And even further maturation and care outside the mother's body can not fix this problem.
From the above, we conclude that tremorChin in newborns up to three months can be quite normal. However, if after this time "trembling" does not pass, parents need to consult a pediatric neurologist, since, most likely, there is some kind of malfunction in the child's body.
And do not forget that a child exposed to tremor needs not only observation from a neurologist and fulfillment of his appointments, but also a friendly environment in the family.
