My son which is 2 years old and i have had diahhrea for 6 days and vomitting only off and on usually when we eat we also have runny noses and no fever?

Sounds like virus: Sounds like a viral "enteritis" - basically a "stomach flu". Viral gastrointestinal infections can not only be tedious to get through, they can also be quite serious in a small child. With symptoms of that duration in a 2 y/o you may need to get reassurance from a pediatrician or urgent care doctor that he/she is staying hydrated enough (as 2 y/o's don't have much reserve). Hope this helps!
