<s>[INST] My 6 month old daughter has lost her voice. When she is able to make a sound, it sounds very raspy and scratchy. She seems to be having a hard time breathing as she sounds very congested. Her nose is running and she has a horrible cough. A lot of drool too because it seems like it hurts her to swallow. [/INST] Hi....looks like a laryngitis or inflammation of the larynx. Usually this will be viral. The best treatment for this is voice which cannot be practised in this age group. But if she develops high fever or inability to feed or breathing difficulty or inspiratory stridor, then you need to take her to the emergency room as soon as possible.Regards - Dr. Sumanth </s>
