newborn’s skull bones are not fused together at birth. Instead, there are spaces between the bones to accommodate the way the baby moves out of the mother’s pelvis. The suture lines on the skull that indicate the location of these soft spots are called fontanelles. These spaces allow the bones to overlap as the baby moves during labor. Therefore, after the baby is born, a safe fontanelle examination is also part of a comprehensive physical examination. So when should you check your baby’s fontanelle?
