Suggest Medication For Cold, Cough With Phlegm, Fever And Diarrhea In A Child

My 7-yr old has colds, cough with lots of phlegm, high fever and diarrhea every time she coughs strongly. It s just been a day. What should I be giving her aside from sponge baths, apple, banana and Gatorade. She also ate rice and meet for lunch today. I gave her paracetamol 5ml every 4 hours if with fever and she s on ventorin (nebulizer). For her cough.
