My whole family got this terrible stomach virus that lasted for about 1-2 days. My 2 year old ended up in the hospital because he couldn't hold any fluids down. They gave him ananti-nausea medication and IV fluids. He stopped vomiting since then, but has diarrhea. This all started 4 days ago. He is acting okay, but I am concerned about him having diarrhea for the past 2 days. Any advice? Has any one's children had a stomach virus for this long?
