Hey there, new parents! If you’ve been gazing at your little one’s head and spotted those soft spots, known as fontanelles, you might be wondering what they are and when they’ll close up. You’re not alone in feeling a bit anxious about them, especially if you notice any pulsing or slight bulging.
What Are Fontanelles?
So, what exactly are fontanelles? They’re the soft, membrane-covered areas on a baby’s skull where the bones haven’t completely fused together yet. At birth, your baby’s skull consists of several bony plates that will eventually come together to form a solid structure around her brain. The most noticeable soft spot is the anterior fontanelle, located at the top of her head, but there’s also a smaller one at the back called the posterior fontanelle.
The Role of Fontanelles
These soft spots play an important role, allowing your baby’s brain to grow and develop during those crucial first months of life. But don’t fret; they won’t remain open forever. Typically, the anterior fontanelle closes between 12 to 18 months, while the posterior fontanelle usually closes by the time your baby is 2 to 3 months old.
When to Be Concerned
If you’ve noticed that the soft spot is pulsing or bulging, it can be concerning. While this can be normal due to the baby’s heartbeat or when they cry, it’s always a good idea to chat with your pediatrician if you have any worries. They can provide reassurance and help you determine if there might be an underlying issue.

Conclusion
To sum it up, fontanelles are a normal part of your baby’s development, allowing for healthy brain growth. They’ll close up as your child grows, so don’t stress too much—just keep an eye on any unusual changes and consult your doctor if needed!
