Those seemingly delicate gaps on your baby’s head, known as fontanelles, play a crucial role in allowing the brain to grow. However, these soft spots won’t remain open indefinitely.
What are Fontanelles?
Fontanelles are the membrane-covered spaces where the bony plates of a baby’s skull have yet to fuse. As your little one develops, these plates will eventually come together, forming a protective hard shell around the brain. The most prominent soft spot is the anterior fontanelle, located at the top of the head, while the smaller posterior fontanelle can be found at the back and typically closes much earlier.
Why Do Babies Have Soft Spots?
The primary function of these fontanelles is to accommodate the rapid growth of your baby’s brain during the first year of life. Although they may seem fragile, these openings are essential for healthy development.
When Do Fontanelles Close?
Generally, the anterior fontanelle will close between 12 and 18 months, while the posterior fontanelle usually closes by the time your baby is 2 to 3 months old.
Pulsing or Bulging Soft Spot
If you notice your baby’s soft spot pulsing or occasionally bulging, it’s natural to feel concerned. This can happen when your baby is crying or straining, but it’s usually nothing to worry about.
When to Worry About Your Baby’s Soft Spot
If you observe any unusual changes, such as a significantly bulging fontanelle when your baby is calm or signs of fever, it’s important to consult a healthcare professional.
