Many current studies (including ours) show that many parents who give their children with eczema and their mothers a longer period of abstinence from food do not experience any reduction in clinical symptoms in their children, and that long-term abstinence from food can affect the child’s growth and development. Therefore, unless a food is clearly found to aggravate eczema, then the food is avoided and the mother and child do not need to avoid it. The way to determine food allergy is as follows: when the condition improves, you can try a food one by one in small quantities, observe for 3-5 days, if no symptoms appear, then eat more, eat more without hair then no need to abstain from eating that food.
