Many children develop large umbilical hernias, and parents should not worry too much. An umbilical hernia is a type of hernia that is more common in newborns and infants. As children grow, the hernia may heal on its own, but it is still advisable to have the child checked by a hospital. If the condition does not improve by the time the child is 5 years old, surgical treatment may be considered. Regular hospitals can provide the appropriate treatment.
