Infant eczema, also known as atopic dermatitis, is mainly caused by an allergy to milk protein, so it is important to pay attention to the child's diet. Nursing mothers should avoid consuming beef, lamb, nuts, and seafood. Additionally, for children who are formula-fed, depending on the severity of the eczema, choose either amino acid formula or hydrolyzed protein formula. The treatment of eczema primarily involves moisturizing the skin. Therefore, applying a thick layer of moisturizer specifically designed for babies on the affected areas can be very effective in treatment. Furthermore, on top of moisturizing, under the guidance of a doctor in a hospital, a weak steroid cream can be used. With the above management, eczema can generally be controlled quickly.
