Question
Is it normal for a child to grow their first tooth at six months?
Answer
Based on the description, this could be a symptom of vitamin D deficiency, manifesting as cradle cap, thinning hair, night crying, and skeletal deformities. It is recommended to start taking cod liver oil from the second week after the child’s birth until they are two years old. It is suggested to administer a vitamin D injection and then switch to oral cod liver oil after a month. It is also recommended to expose the child to more sunlight.
