If there's a stinger, remove it by scraping it out with your fingernail or a credit card. (Pulling it out with your fingers or tweezers could squeeze more of the venom into your baby's body.)

Wash the area thoroughly with soap and water. You can help relieve any swelling or itching by applying an ice pack, calamine lotion, or a paste made from baking soda and water.

If your baby seems very uncomfortable, ask his doctor about giving him the appropriate dose of acetaminophen or ibuprofen. Never give your child aspirin, which can cause a rare but potentially fatal condition called Reye's syndrome.
