The baby should not be overfed, so as not to aggravate the gastrointestinal burden, lead to digestive dysfunction and aggravate eczema. Mom doesn't have to restrict all "sensitive foods" unless the allergen is clear. Dietary avoidance tests can be conducted for several "suspected" foods such as milk and milk products, eggs and seafood. After avoiding these allergic foods, infantile eczema improved or disappeared. It is considered that eczema is related to the mother's eating of these foods. If the allergic symptoms do not improve after avoiding these allergic foods, mother can try to eat only rice, vegetables and bean products for the time being. After the baby's allergic symptoms are relieved (usually a few days), the mother can restore the food one by one, observe each food for 2 to 3 days, and add the next food when there is no special situation. When your baby's eczema gets worse, you can roughly determine the allergen and avoid the food for at least 2 to 3 months.
