My 9 month old daughter has cold she's coughing a lot and bcoz of phlegm she cat breath properly n also her fever is increasing I'm giving her advil (ibuprofen)?

Bacterial. I''m not sure how long these symptoms have been going on, but it is certainly possible that she has developed a secondary bacterial infection involving her ears, sinuses and/or chest. She should probably be evaluated by her doctor to determine whether she needs an antibiotic.
