So I once had a patient who called worried and asked me "My baby drank some soapy water when she took a bath, should I be concern? Will soap come out from her butt?"
My response "Well... She should be fine dear. I do not believe you see soapy water come out of her butt. But if you do, I wish I can be there to see that! ???."
Note: Don't worry I advised her what to do in case of any issues.
