Keep your baby's face clean. Wash your baby's face daily with warm water and mild baby soap. Dry your baby's face gently. Simply pat your baby's skin dry. Don't pinch or scrub the acne. You may cause more irritation or an infection. Avoid using lotions or oils on your baby's face. i hope this helps
