She's been sick. I'm not sure exactly what it is--no obvious symptoms (eg diarrhoea, runny nose, etc). She's just feverish and clingy, and has a little bit of a cough. I thought she was better today (she was much cheerier and was running around) but at dinner time her fever came back (38.5) and she got all sleepy and clingy again. So it's back on the Calpol. I have one of those syringe things for giving her medicine, and she's not impressed.
