Question?

Has anyone's kids ever had Rotavirus?? Well, that's at least what I think Ollie has. He has had constant diarrhea for the past 5 days, and this is not normal stuff. It's really runny and it pretty much leaks out of whatever diaper I put on him and gets to every outfit. It happens about 7-10 times a day, not always severe but usually pretty bad. And he's been throwing up, not constant, probably like 5 times over the past week. And just today he is unbearable, like cannot be entertained or made happy at all. His is a very sad baby, it breaks my heart. So when I went online to do a little research that's what I came up with. It's most likely something he got from my work, of course, cause every week we are sick with something new, ridiculous. So my constant thing is do I go to the doctor? Cause everytime it seems I've gone to the doctor they are useless, they never tell me anything other than what I already know. He's not dehydrated, I think that's the main concern but still, this isn't normal. Any help? And actually, I should add the ONLY thing that makes him remotely content is baby einstein, this is a mom's dream product I tell ya!
