Our GP just rang and said that the blood work done because ds2 is exhausted, pale and emotional suggests that his thyroid may be the culprit.
Further tests are being done by the lab and we should hear more tomorrow morning.
He has been really out of sorts for the past 2 weeks on the heals of a nasty cold and gastro bug. He is so tired that he naps at least once a day (very unlike him) and still spends 12 hours in bed at night before needing to be woken in the morning. He hasn't been back to nursery for 2 weeks because he can't make it through a morning at home without falling asleep.
