The baby’s body itches at night when he sleeps should pay attention to the following situations: First, we should pay attention to whether we are allergic to the sleeping quilt, pillow, etc. We should go wash the quilt and pillow in the sun when the sun comes out and expose them to the sun, which can eliminate the mites and other allergic substances on the quilt and pillow. Second, we should pay attention to whether we ate allergy-prone food before going to bed, for example, common allergens are eggs, milk or other allergens, and if we eat allergy-prone food will also cause itching on our bodies when we sleep. Third, pay attention to the baby may itself be highly allergic to the body, in the night when the temperature drops at bedtime will also feel more prone to itch than the average baby, prone to allergy symptoms.
