When Does a Baby’s Soft Spot Typically Close?
Although the timing varies, you can generally expect your baby’s posterior soft spot to close by 2 to 3 months of age, sometimes even at birth. This posterior fontanelle is one of the baby’s soft spots that pediatricians monitor closely.

How to Monitor Your Baby’s Soft Spot and When to Get Help
Keeping track of your baby’s soft spots helps you understand their growth and spot any potential issues early.
Regularly monitor the soft spot’s texture; it should feel soft and flat with gentle pulsation, indicating normal blood flow.
