For your 14-month-old, washing the burn gently with lukewarm water and a mild, unscented soap is safe and sufficient; a specific medical cleanser is unnecessary unless prescribed. After applying Silverx gel, you should cover the burn with a sterile, non-stick dressing rather than leaving it open. A dressing keeps the medication in place, protects the sensitive area from friction and dirt, and prevents infectionwhich is especially important for an active toddler. Change the dressing daily or as directed, and contact his pediatrician immediately if you notice increased redness, warmth, swelling, or pus.
