Itchy patches that keep coming back in a child are often due to a skin condition like eczema or an allergy, in which the skin becomes dry and sensitive. It improves with cream, but returns because the underlying dryness or trigger remains. Keep the skin well moisturised daily, use gentle soaps, and avoid triggers like heat, sweat, or harsh products. A doctor can guide you to the right cream and a long-term care plan to control it and prevent frequent flare-ups.
