Greetings umbilical hernias resolve on their own by age 1. Keep the area clean and dry, washing it gently with water during regular baths. Never use coins, tape, or tight binders to push the bulge down, as this harms the skin. The bulge may look larger when your baby cries, coughs, or strains, which is completely normal. Seek immediate medical care if the navel becomes discolored, very tender, swollen, or hard.

Will resolve by 1 year of age If any discharge is there, becoming hard/red/tender should visit your pediatrician
