The most common type of eczema is atopic dermatitis. It is most common in babies and children but adults can have it too. As children who have atopic dermatitis grow older, this problem may get better or go away. But sometimes the skin may stay dry and get irritated easily.
Signs and Symptoms. Signs and symptoms of eczema can vary widely during the early phases. Between 2 and 6 months of age (and almost always before they're 5 years old), kids with eczema usually develop itchy, dry, red skin and small bumps on their cheeks, forehead, or scalp. The rash may spread to the arms and legs and the trunk, and red, crusted, or open lesions may appear on any area affected.
