This is a normal physiological manifestation of chin tremors in children, especially when they have just fallen asleep or when they are not concentrating on feeding, this is a normal physiological manifestation, the vagus nerve excitability is too high, the child’s control ability is poor, it is easy to appear such a situation, this is a normal physiological phenomenon, so do not need to do any treatment. If there is more frequent jaw tremors, and the baby is always crying, there is a history of hypoxia at birth, then it is possible that the child has cranial brain injury, we need to take the child to the children’s hospital neurology department to do a cranial magnetic resonance and electroencephalogram test; if there is obvious brain damage, and ruled out epilepsy, we give the child active rehabilitation training, the earlier the effect of treatment, the better. Therefore, jaw tremors are classified as physiological and pathological. Physiological ones do not need to be treated and can be relieved after 6 months of age, while pathological ones need to be diagnosed and treated in a timely manner, and within 1 year of age is the best time for treatment, so don’t miss this time.
