The soft spot on the top of a baby’s head is called the anterior fontanelle. The anterior fontanelle is usually about the size of a rupee coin. The skull of the newborn is made up of loosely arranged bones with some gaps. The anterior fontanelle is the biggest of these gaps. As the skull enlarges, the gap fills up, getting smaller by 6-9 months and closing completely by one and a half years. It normally is level with the rest of the bony skull and may show a gentle rising and falling movement.
