Re: HELP me stop the...
How old is she? If she is old enough for solids try the BRAT diet. Bananas, rice, applesauce(natural, no extra sweetner), and toast. But stay away from apple juice, the sugar in juice only feeds the virus and causes more diarrhea. If she is still vomiting us clear liquids only, broth, juice(again not apple, white grape is best), water.
Main thing is to make sure DD doesn't get dehydrated which can happen relatively fast, hours not days.
Sorry I don't know how to tell you to keep it contained.
Try to get some banana in her fast that always keeps my DD regular.
