About 2 weeks ago my 4 year old toddler started shaking at night after a few hours of being asleep. He seemed like he was having a nightmare, he would sit up on his bed and start shaking almost as if he was to be cold only it wasn't cold, it was actually hot. He would be making weird noises like he was complaining of something, I even noticed that he had his eyes open, I would call his name to see if he would respond, and no response. He did that about three nights in a row. I took his to his pediatrition, she said it was most likely night terrors, nothing to be concerned about. He did stop for a day or two, but then again he started with the same incidents, only this time I also noticed that his pillow was drenched in sweat, this has been going on and off now at nights.
