my 5 year old has had vomiting diarrhea for the past 7 days, i have been giving him the brat diet and that has stopped the watery stools, he will eat a little and hour or so later up it will come. yes he is drinking water, sprite, and that stays down, he seems find for about 5 hours and he eats and we start the whole thing all over, he is urinating, but only weighs about 36 lbs, is this a virus or is there something else going on
