One of the measurements taken during your baby’s checkups is baby head growth or head circumference. Like height and weight, head circumference is recorded on its own chart. Your baby's brain growth is reflected in the size of his skull. The skull of a baby is made up of several bones that are not fully joined to allow for this growth.
Your doctor will be concerned if your baby’s head is growing too slowly or too quickly. It is important to have your baby's head circumference measured regularly. The rate of head growth is what you want to focus on, rather than the actual size itself so that either the slowing down or acceleration of head growth can be treated if needed.
Measurements are always adjusted for babies who were born prematurely.
To measure your baby's head, a flexible measuring tape is placed around the area just above your baby's eyebrows and ears which is the part of the head that has the largest circumference.
