This sounds to me like the stomach bug that is going around. Both my kids and myself have had it. It is not a bad one, but my pedi said it is lasting about a week. Sporatic vomiting and diareah that comes and goes for up to 7 days. She said there is no rhyme or reason for why it is lasting this long and why one day they can have no symptoms then the next they do. Bananas, applesause, and rice cereal will help her stomach. Carrotts help with diareah. Also, peach juice from canned peaches with help settle her stomach and queasy feeling, 1 tsp every few hours. If it last more than 7 days I would call your pedi or if you can't keep any formula or pedialyte down her either. Also, watch her diapers, with a stomach bug you should have at least one wet diaper every 6-8 hours. My pedi told me she had 45 kids that were sick with this bug last week. Every child is different, so go with your gut on what you think you should do.
