Re: What could this be? may be tmi...
Could also be flu or rotavirus. My son did the same things with both of them and never ran a fever. They did the test and it came up flu and the rotavirus they just diagnosed which the main symptom is watery diarreah(sp) then vomiting. I would call the pedi just to make sure. Other than that all you could really do is pedialyte and formula. They told me to continue to give the formula unless he wouldn't take it but he took it the whole time with no problem.
