My child sucks his thumb - how can I prevent infection?

To prevent infection from thumb sucking, it is important to first try to limit the habit of sucking the thumb. Clean the cracked skin with water and a mild, unscented soap. Applying a moisturizing cream can help heal the crack. Avoid using antibiotic ointments unless the wound is infected. If the wound becomes more seriously infected or if the person develops general infection symptoms like fever, it is recommended to see a doctor. Hope this helps!
