Question
Is a head circumference of 43cm normal?
Answer
A head circumference of 43cm may be normal in certain situations, but it ultimately depends on the child’s age, gender, and growth development. Generally, a newborn’s head circumference is about 33-35cm, with the fastest growth rate during the first year, averaging an increase of about 1.2-1.3cm per month. In the first two years after birth, the head circumference will increase by approximately 12cm. However, each child’s growth varies greatly, so it is best to consult a pediatrician to determine if the child’s head circumference falls within the normal range. Additionally, one can comprehensively evaluate the child’s health condition by observing their growth curve, dietary habits, and developmental milestones.
