Prevention: Mom should eat less shrimp and crab food and all kinds of raw and cold food.

Nursing: If you can't change the baby's diaper and clean the buttocks in time, it may cause red buttocks and even local infection. Therefore, you have to change the diaper as long as it is wet. Every time you change the baby's diaper, you should also clean the buttocks first, and apply hip cream if necessary to protect the local skin. With the increase of age, infants' physiological diarrhea will heal itself without treatment, and generally no medication is needed.
