It is important to keep your child’s feet clean and dry to prevent infection and cracking. A dermatologist or podiatrist can best determine and treat the condition. However, the best solution for cracked feet is to keep your feet hydrated and moisturized. This can be done by using lotions and creams specifically designed for cracked feet. You can also soak your feet in warm water with Epsom salts or other moisturizing oils such as olive oil or coconut oil.
