[|Human|] My four year old has had a cold, clear runny nose and cough for the last 3 weeks.  She has vomitted every Saturday for the last 3 weeks.  No smell to the vomit, just food.  Took her to the doctor on Monday they said it was a cold/virus.  Should I take her back to the doctor?  Do you think she needs an antibiotic?
