My little boys 3 he's been unwell for a few days now I took him to the doctor the night before last and he basically said keep an eye on him he should feel better in a week or so with calpol often. I've been monitoring him today and all the poor baby wants to do is sleep he had 12 hours last night and hasn't managed he stay awake for longer than 30 minutes a time today, he's drinking not eating, has an awful cough and a temperature is this concerning or expected behaviour?
