For quite some time now I have noticed that after a couple of hours of sleep DS's head his soaking wet. It is as if someone has poured a jug of water over him and his pillow is drenched. It seems to just be from his hair (which is short), his face is fine and so is his body. He is fine and well in all other respects and this never happens during the day. It doesn't happen every night but probably every other.
Obviously I make sure that his room is not too warm and he sleeps in the coldest room in the house. Has anyone else had this problem and is it just a normal thing or should I mention to the Dr?
