Supra-umbilical hernias are less common than umbilical hernias. They occur as a result of a defect just above the umbilical ring. Though a majority of umbilical hernias close spontaneously by about 3 years of age, some of them may not and require surgical closure. Supra-umbilical hernias, on the other hand, do not close spontaneously and need surgery. In any case, there is no urgency and you may still wait for a few more months, unless the hernia is increasing in size.
