Treating allergic urticaria in children usually requires comprehensive management to alleviate symptoms and reduce recurrence, but it is difficult to achieve a complete cure in the short term. It is recommended to gradually control the condition under the guidance of a doctor by avoiding allergens, using appropriate medications, and maintaining good daily care.

Specifically, we can start from the following aspects:

1. **Identify and avoid triggers:** Observe the food, items or environment your child came into contact with before the onset of the illness, such as pets, pollen, certain snacks, etc., and minimize contact as much as possible.
2. **Use medication as prescribed by your doctor:** Doctors often recommend using anti-allergy medications to relieve itching and redness. Please strictly follow the prescribed dosage based on your age and weight, and do not increase or decrease the dosage on your own.
3. **Pay attention to skin care:** Keep your child's skin clean, dress them in loose cotton clothing, avoid scratching, and do not use excessively hot water when bathing them.
4. **Stabilize emotions and routines:** Ensuring children get enough sleep and appropriately diverting their attention from itching can help reduce flare-ups.
In daily life, parents can record their child's diet and environmental exposure to help doctors determine the cause of the allergy. If hives recur or are accompanied by severe symptoms such as shortness of breath, medical attention should be sought promptly to adjust the treatment plan. With patient care and long-term observation, most children's symptoms can be effectively controlled.
