<s>[INST] I have a 41/2 month old who has been recently sick with RSV and then immediately after getting better from that, she started vomiting. Now the vomiting is only brought on by an occasional cough, but she has voluminous pale yellow, kind of spreadable stool that smells grossly like fish. The stench fills the room! She has seen the doctor for the vomiting, but not for the stool. I feel like an idiot making appointments every week (new mommy!). What could this be? [/INST] Hello, According to the symptoms, the loose stools and vomiting look like a viral infection. I would suggest symptomatic treatment with adequate fluids. As viral infections recover on its own within a few days to two weeks. I would advise you to meet your pediatrician for the prescription of an anti-emetic, probiotics, and examination. Home remedies such as soups, fluids, yogurt are the best. Hope I have answered your query. Let me know if I can assist you further. </s>
