You can use SILVER ointment for external application for relief of pain, and it can be soothing. It seems your kid is having viral diarrhea. Once it starts it will take 5-7 days to completely get better. Unless the kids having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting. You need not worry. I suggest you use zinc supplements (Z&D Chat Doctor.  </s>
