How to deal with a child who bites people?

Patient's question:

No

Doctor's answer:

Consider the possibility of a deficiency in trace elements.
Opinion and Suggestions:
It is recommended to test for trace elements to see if there is a deficiency in zinc or calcium.
If zinc is deficient, consider taking gluconate zinc.
If calcium is deficient, consider taking (a children's calcium supplement).
Monitor the situation and also consider taking traditional Chinese medicine preparations for regulation.
