Edit the image while keeping the exact same composition and realistic style. The baby remains shown from the back, wearing a premium white Pampers-style diaper with a clean black Nike logo clearly visible. Replace the dangerous object with a small child-friendly water gun/toy gun, placed naturally in the scene. Do not modify the toy gun. Keep it exactly as it is in the original image, preserving its shape, position, and details. Keep the natural lighting, realistic shadows, skin details, and original atmosphere. Professional photography style, ultra-realistic 4K quality, high definition, natural look, no artificial effects, no changes to the baby’s identity or the original composition.
