What to do and when?

My daughter is three and has had a yellow stool for a week or so and is complaining her belly hurts sometimes. She has had a runny nose and cough for this time as well but now her nose has dried up and she is vomiting and having lots of stools and they are all still yellow. When and what should I do and be concerned about? Please help!

Welcome to the gastroenterology community!  She really needs to be seeing a doctor about this.  She needs to be checked out to make sure something serious isn't going on.  In the mean time she needs to stay hydrated.  Have her drink something like pedialyte to make sure she doesn't get dehydrated.  Good luck.
