Paraumbilical hernias do affect children differently than adults. Paraumbilical hernias that develop within the first six months of an infant's life usually heal before the infants is age one. Larger hernias that develop during the first year of life often heal before the child is four years-old. Paraumbilical hernias that form in adults require surgery. Adults may also have pain or discomfort associated with their hernia, whereas a paraumbilical hernia causes little to no pain in children.
