My 18 month old has been unwell for 4 days now. It started with vomiting and since then she has vomited once or twice a day. She also has a pronounced cough and has had a temperature of around 38 intermittently (seemed hot once or twice a day but went down with Calpol). Anyone know what this could be? Thought stomach bugs were over quickly so I guess this is something else. Maybe the coughing and accumulation of mucus causing the vomiting? Would you seek medical help or wait it out. She has been quite lethargic and mostly wanting to sleep on me and not eating much. Not dehydrated as still drinking.
