I'm worried 😢

Na

My baby was throwing up yesterday.. milk and solids..this morning she woke up with a light fever and running nose.. I took her to the doctor and her pediatrician said she couldn't give her a diagnosis yet because her did not have diarrhea.. just to make sure I keep her hydrated.. and if she continued wth fever and vomiting to take her to urgent care.. she has not vomit anymore.. she eat chicken soup and had some milk...and advice?????
