question: Hi, may I answer your health queries right now ? Please type your query here... my daughter is almost 4 and has had really bad breath for a few weeks now along with a slightly bloody nose. I believe it to be the dryness in the air. I have tried brushing, mouth wash and started today with a humidifier. I am a little anxious that it may be something more serious. No other symptoms...no runny nose or cold, only the breath and blood in her nose.
