It is normal for the posterior fontanelle to close by 8-12 weeks after birth. As the infant grows, the cranial bones naturally fuse together, and the fontanelles close. The anterior fontanelle usually closes by 18-24 months, and the posterior fontanelle by 8-12 weeks. Therefore, it is not a cause for concern if the posterior fontanelle cannot be felt in a 16-week-old infant. However, if the mother is still concerned, she should bring her infant to the clinic for a check-up.
