If a baby has eczema, it still needs to be treated actively, as eczema can cause discomfort for the child, who may repeatedly scratch the affected skin area. First, it is essential to maintain hydration, using a thick layer of moisturizing cream specifically designed for infants. Additionally, depending on the severity of the eczema, some mild topical corticosteroids can be chosen to effectively control the condition. Diet control is also very important. For breastfed infants, mothers should avoid consuming beef, lamb, nuts, and seafood. For infants on formula, depending on the severity of the eczema, amino acid-based formula or hydrolyzed protein formula should be selected. As children grow, most will see an improvement in eczema after the age of one. For severe cases that persist beyond the age of one or two, it may be necessary to consider an allergic constitution and actively search for allergens to undergo desensitization treatment.
