I am experiencing the same thing with my daughter! I have been trying to figure out why, after a nap and after a night of sleep, she feels so hot. So I take her temp and its anywhere from 99.8-100.9...I take it with an ear thermometer and then she cools down after being a wake for awhile. It troubles me because your body temp is supposed to cool while you sleep. This happened before and my pediatrician said nothing and couldn't explain it. Have you found out anything else regarding this?View Thread
