My son is 2.5 and he sweats excessively when he naps and sleeps at night. He sweats quite a bit when he plays outside too but it's warm and he plays rough so that makes more sense. We try to keep his room fairly cool, we use central air and he has a ceiling fan. He does sleep with his dream blanket on him, he insists.

He went to bed a little over an hour ago and just called me very calmly a few times, when I went him he said "I wet, my pillow wet." Sure enough he was soaked and his pillow was soaked. I changed him and the pillow and he was happy the whole time, happily got back in bed. I don't suspect he is sick but this has been going on for a few weeks- with the warm weather. But is this unusual? It seems like a ton of sweat. Should I be worried or call the doctor?
