For children with urticaria, it's advisable to choose light, easily digestible foods and carefully observe for potential allergens. Here are some specific points:

1. **Prioritize mild foods:** such as rice porridge, soft noodles, steamed vegetables, and apple puree. These foods are gentle on the stomach and intestines and help the body recover.

2. **Supplement protein appropriately:** If the child does not have any food allergies, they can eat some cooked chicken, fish, or tofu, but the cooking should be as light as possible, avoiding frying or spicy seasoning.
3. **Be aware of foods that may trigger allergies:** Foods such as seafood, nuts, and mangoes may worsen symptoms. During an attack, you can temporarily reduce or avoid these foods and gradually try them again once your skin condition has stabilized.
4. **Ensure adequate hydration:** Drink plenty of warm water or light soups to help your body metabolize, but avoid sugary drinks or cold beverages.
Finally, a reminder to parents: every child is different. If hives recur, it is recommended to keep a food diary and consult a doctor to find a suitable diet for your child.
