My son turned 3 in july, for a month now for 1 to 3 days a week he is having what we are calling episodes.
basically, he is moody, lethargic, hot but claims he is cold and begs for jumpers and blankets, sleeps alot lot more than usual (normal is 7.30-7.30 at night and 2hr nap) during the episodes he can sleep 6hrs in the day and be in bed by 5-6 and sleep through until disturbed by dds antics.
the first time, dd had the same symptoms and the on call doctor diagnosed croup, but they were coughing. DD is 100% fine, ds is worrying.
when he is well, he is bright, very active and extremely healthy, he has a fantastic diet and i have no concerns, he is literally changing over night suddenly once a week.
a visit to the docs asked for a urine sample, should be fun, he isnt potty trained. and gave me some rubbish that his immune system is developing and that 'might be it'
im absolutely terrified.
