Home Care

If the fontanelle returns to normal appearance when the child is calm and head-up, it is not a truly bulging fontanelle.


Call your health care provider if

Immediate, emergency care is needed for any infant who has a truly bulging fontanelle, especially if it occurs along with fever or excess drowsiness.


What to expect at your health care provider's office

The health care provider will perform a physical examination and ask questions about the child's medical history, such as:

  • Does the "soft spot" return to normal appearance when the infant is calm or head-up?
  • Does it bulge all the time or does it come and go?
  • When did you first notice this?
  • Which fontanelles bulge (top of the head, back of the head, or other)?
  • Are all the fontanelles bulging?
  • What other symptoms are present (such as fever, irritability, lethargy)?

Diagnostic tests that may be done are:

  • CT scan of the head
  • MRI scan of the head
  • Spinal tap (lumbar puncture)
