My eight year old daughter, roughly three times a winter seems to get a stomach bug. She has a temp that will be there in the morning then gone all day and come back the next day and so forth, she has very stinky/bad gas, is tired, doesn t feel like eating and periodic vomiting . I was wondering if there is a name for this illness and some way to help this sickness to leave quicker or to prevent it altogether? Thank you for your time:)
