Hi. My daughet is 8 years old. Three weeks ago on wensday she complaint about stomach ache and vomited. It seems like chunky pieces of food and after a couple of hours she seemed to be fine no belly poain and she ate pretty well. So the next day I send her to school but there she vomited again. Came back home and she seemed to be ok again. Two weeks ago she was complaining about stonach ache again but didn't throw up. Last week she was in school and she again complaint about stomach ahe and voimited. After 4 to five hour she was fine and also during the week end. She doesn't have any fevere or diarrhea. Do you have any idea what might cause this?...
