Infant umbilical hernia is a congenital developmental disorder caused by a weak abdominal wall at the navel present from birth, which especially tends to bulge when intra-abdominal pressure increases. Of course, bathing is permissible as long as there is no local skin infection around the hernia; there are no issues with bathing otherwise.

However, if there is local skin infection or damage at the hernia site, caution should be taken during bathing to disinfect properly and avoid irritating the wound, which could worsen the symptoms. Indeed, over 80% of umbilical hernias can heal naturally before the age of two as the child grows and develops. Only a small fraction of children, whose hernia ring diameter is larger than 2 cm or who still have a noticeable umbilical hernia after the age of two, require surgical treatment.
