See Your Doctor Now: Malodorous breath in an infant is unusual and you have indicated the presence of “flu”. More information is needed e.g. duration/description of other symptoms present, vomiting, appetite/stool abnormalities, past medical/family history, and more. Physical exam is crucial to provide more diagnostic clues. See your doctor now for further evaluation and correct diagnosis/treatment.
