My 5 year old daughter had astomach bug a week ago, threw up for about 6 hours, thenslept a LOT, had a few slow days, but by day three, was her normla self. Now, here I am a week later, no vomiting, but really lethargic (wants to just lie down , even on the bathroom floor waiting for a tub). Has tummy ache but no vomiting. Eating chicken soup, ginger ale, popsicles, had a banana yesterday.
