question: My son had a slight fever on Wednesday of last week, it seemed to be gone the next day, as he seemed much better as well. However, Sunday night he got a heavy flem-like cough that only lasts for 20-30 minutes but it made him vomit at the end of the night while he had fallen asleep. The cough gets bad while he s sleeping (for a short period of time), and I m not sure if he s swallowing the flem OR if there isn t much flem for him to spit. We gave him cough & cold syrup as of Sunday & gave him fever reducing Advil syrup as of yesterday. Should we keep doing the same or should we be addressing something else?
