Has something like this happened to your babies? My 8 month old is vomiting and has diarrea and is vomiting since Monday. That same days we had tests on him done, and everything came back negative (no rotavirus, no infections, no amoebas). The ped. said it was some sort of virus that is in the environment and that it should go by itself in around 3 days. All day yestarday he didn't vomit or evacuate, but at night he did again. He has been very down and he doesn't wanna eat anything. It's very frustrating to see him like this, he's a very active baby and just seeing him like that kills me :(

I don't know what else to do, two doctors have checked him and say he doesn't have anything to worry about, just that virus...but what is it? Has anyone gone through this?

Summarized question: What would cause vomiting and diarrhea 8-month-old if all the tests are negative and had anyone experience the same with their babies?
