Ds had quite a deep cut took him to injury unit, no stitches needed. They gave it a good clean and put an iodine dressing on, then some gauze and a bandage over it. I have spares to change the dressing, the nurse said when he gets a shower change the dressing. I stupidly didn't ask but does anyone know how long that should be? 2 days, 3 days or should I leave longer to heal or change quicker so its clean?
