Question
Why does an 8-month-old baby frequently bite their upper lip, and sometimes shake?
Answer
Biting one’s own lips in a baby might be due to a lack of security, which is a behavior seeking for security. If the baby is very young, they may lack vitamin D, which can lead to hypocalcemic convulsions. The treatment usually involves supplementing with medications containing vitamin D and calcium, under the guidance of a doctor. It is recommended that parents take their child to see a doctor for a clear diagnosis and treatment plan.
