Understanding the Soft Spot
The soft spot on a baby's head, known scientifically as the fontanelle, is an area of the skull that is not yet fully fused. Newborns have two primary fontanelles: the anterior fontanelle and the posterior fontanelle. These soft spots are covered by a tough membrane that protects the underlying brain while allowing for growth and development.
The anterior fontanelle is the larger of the two and is located at the top of the baby's head, near the forehead. It is diamond-shaped and usually measures about 2 to 3 centimeters (about 1 inch) across. It also takes the longest to close up, which happens around 18 months of age. The posterior fontanelle is smaller and located at the back of the baby's head, just above the neck. It is typically triangular in shape and tends to close earlier than the anterior fontanelle, at age 2-3 months.
Importance of the Fontanelles
Monitoring and Care
Most of the time, fontanelles close naturally and without complications. However, it is important to monitor their size and how they feel. If the fontanelle seems unusually bulging or sunken, it could indicate a health issue, such as dehydration or increased intracranial pressure. In such cases or if you notice any other changes, as always you should consult your pediatrician for guidance.
Understanding the soft spot on your baby’s head helps ensure you provide the best care. Always remember, while the fontanelle is an important part of your baby’s development, it is only one aspect of their overall health.
