Good day! The child has dry forehead, there are also such dry spots on the body, on hands and feet. The doctor said to use cream during bathing (2 photos) but it doesn't help us. A regular baby cream also doesn't help. Is this just dryness or could something else be going on? The humidity at home is normal, we keep track of that.
