Question
The baby suddenly has fixed eyes and doesn’t respond when called, which might be a sign of a tic. The causes can be numerous, such as vitamin D deficiency disrupting calcium metabolism leading to tics, or brain disease caused by difficulty breathing at birth, leading to brain edema, which can also cause tics. Eating the thumb is a form of self-soothing for the baby.
Answer
It is recommended to quickly visit a regular hospital to determine the cause of the baby’s tic. Providing more affection to the baby can increase the frequency of thumb-sucking.
