Question
A schoolboy was pointed out by his teacher for frequently chewing his fingers and biting his red scarf, but this behavior is rarely observed at home. What could be the possible reasons, and how can this behavior be corrected?
Answer
When children display the behavior of chewing their fingers and biting red scarves at school, it may be related to deficiencies in trace elements or poor habits. Firstly, it is necessary to have the child undergo trace element tests, and treatment should be administered according to the test results. At the same time, attention should be paid to correcting these bad habits in a timely manner.
