An umbilical hernia is when the abdominal content pushes through a defect in the belly button and creates a large "outy" belly button. They are usually first noticed soon after birth and may be more prominent when your child coughs, cries or strains. Unlike inguinal hernias the risks of complication of an umbilical hernia are much lower. Most umbilical hernias will close by themselves by 3 years of age.
Should your child's hernia not close by 3 years of age it may require surgery to repair the abdominal wall defect.
