If standard rash creams are ineffective, many parents find success using cold-pressed coconut oil, which is natural and soothing for sensitive skin. Apply a generous layer at each change and avoid wiping it off entirely. Additionally, switching to a portable bidet for cleaning instead of chemical-laden wet wipes can significantly reduce irritation. Ensure you are using highly absorbent diapers and give your baby frequent 'diaper-free time' to allow the skin to breathe and recover.
