Question: My son will be two years old at the end of this month. His physical development is good, his appetite is also good, and he can speak some simple words. Why hasn’t his fontanelle fully closed yet? Will late closure affect his health?
Answer: No, it won’t. The timing of fontanelle closure varies from person to person. In fact, closing too early is not beneficial for infants. Most babies’ fontanelles fully close after the age of three, which is conducive to brain and skull development.
