The incidence of baby red bottom is high, and some serious babies even need to be hospitalized. Once a baby has a red bottom, it is often tricky, especially in winter, it is more difficult to heal and easy to repeat, and the baby’s bottom is stimulated by urine and stool for a long time and only the local skin is red and broken. Babies with diarrhea, premature babies, low birth weight babies, and when babies start to add complementary foods are prone to red bottom because of the high number of stools. Therefore, red bottom needs to be prevented: Step 1: Change the diaper in time after each bowel movement, wash the baby’s bottom with warm water first, then dry the water drops with a soft tissue (do not use too much force, the baby’s bottom is delicate and the skin is easily broken). It is not recommended to put on the diaper immediately after drying the water drops, you can wait for a moment to wait for the buttocks to fully dry. Step 2: After drying the buttocks and then apply a layer of skin protectant (such as buttock cream or petroleum jelly) on the buttocks, which can play a role in isolation (to prevent the next urine and stool on the buttocks skin irritation), and then put on the diaper. If you have enough manpower, you can consider not wearing a diaper to effectively keep your buttocks dry. Step 3: In case of red buttocks or buttock buttocks breakout, it is recommended to temporarily stop using buttock cream, and if redness is obvious or inflammation is present, appropriate anti-bacterial drugs can be used for topical application.
