How can I stop my child from biting their nails?

Patient's question:

No

Doctor's answer:

Children sucking their fingers or biting their nails is generally not due to a lack of certain trace elements in their bodies, but rather a habit issue. It is more common in children aged 3 to 6. Most children will naturally stop biting their nails as they grow older, while a few stubborn ones may continue the habit into adulthood.
