Umbilical cord care: Clean around the cord stump with plain water and blot dry until the stump dries up and falls off, usually in 10 days to 3 weeks. Don’t let the belly ʙuттon area soak in water until the stump falls off and the area heals. Before the cord stump falls off, it will change color from yellow to brown or black — this is normal. Call your doctor if the area looks red, has a bad odor, or has discharge.
Circumcision care: After a circumcision, doctors usually put petroleum jelly on the tip of the baby’s penis and cover it with gauze to keep the wound from sticking to the diaper. At each diaper change, gently wipe the tip clean with warm water (not a baby wipe), then apply petroleum jelly and gauze. Penis redness or irritation should heal within a few days to a week. But call your baby’s doctor right away if it gets worse or if pus-filled blisters form. These can be signs of an infection.
