Video: Baby's soft spots (fontanels) A baby's skull consists of several bones, and there are soft spots â or fontanels â where they meet. A baby's soft spots are covered by a thick fibrous layer. The soft spots are safe to touch and typically close within 12 to 18 months, when the skull bones fuse together. June 28, 2016.
The anterior fontanelle is more obvious and can be easily felt as a slightly soft area of skin on the top of the head. This does not close until well after your baby's first birthday, usually after 18 months. Keep an eye on your baby's fontanelles. They can give important clues to the state of her health. Sunken fontanelles may be a sign of dehydration. Bulging fontanelles can be a symptom of a serious illness, such as meningitis.
