9 month coughing

DD has had this kind of raspy cough for the past two days. it started the day before yesterday and i didn't do anything about it because she had her well check up yesterday. i mentioned it while we were there and the nurse practitioner said it seemed like nasal drainage. sounds nasty. lol. it's not a persistent cough, though. she SOUNDS like she's wheezing a bit, but her lungs are clear, so that's good. she has no temp or anything either. i was just wondering if there's something i can do for her to help clear it up. she seems fine and everything, i just want to help get rid of it if i can.

any ideas?
