Suggest Treatment For Cough, Vomiting And High Temperature In A Child

My daughter, 4, usually very energetic has been lethargic today after waking with a chesty cough. She says it hurts when she coughs although she hasn t coughed much throughout the day. She coughed earlier and vomited some thick pink-coloured mucus (could be colouring from Calpol medicine I had given her prior to this). She has a high temperature and is very out-of-sorts. She has woken almost every night in the past week crying but delirious when we talk to her and in the morning she has no memory of it -Probably something that s been coming all week?
