What can be done for umbilical hernias?

Surgery: No other way to fix a hernia.

Depends on situation: If a newborn, you can often wait until they begin being more mobile to see if it will self correct. I see more female than male infants that need it fixed with surgery & usually wait until they or 2-3y before proceeding with surgery.The strap muscles that provide the "6pack" are loose during early infancy, yet as they firm up the hernia often disappears.Otherwise surgeons can fix it.

Watched vs. surgery : If asymptomatic, nothing. Can leave it alone. Especially if small and not changing over the years. If painful, large or increasing in size better to have surgery and fix it before it gets large. Usually an outpatient surgery with a small cut below your umbilicus.
