For minor burns:
Cool the burn to help soothe the pain. Hold the burned area under cool (not cold) running water for 10 to 15 minutes or until the pain eases. Or apply a clean towel dampened with cool tap water.
Remove rings or other tight items from the burned area. Try to do this quickly and gently, before the area swells.
Don't break small blisters (no bigger than your little fingernail). If blisters break, gently clean the area with mild soap and water, apply an antibiotic ointment, and cover it with a nonstick gauze bandage.
Apply moisturizer or aloe vera lotion or gel, which may provide relief in some cases
See your doctor if your baby develop large blisters.
