I can't remember how it affected DS1, but DS2 has been asleep all day bar an hour at lunchtime and half an hour earlier. He just managed to sleep through being put in the car, dragged round tesco, being prodded by DS2 and is still asleep, will have to wake him shortly for feeding. I haven't given him any calpol yet either as i don't think he's really had a temperature, but perhaps I should.
Should I worry?
