Multiple nights a week we are awakened by my 19mo. old whining and moaning in his sleep and instead of calming down, he only gets louder and louder the longer we wait. Most times waking him up, rubbing his back or giving him some milk helps, but it just continues to happen. He's a very stress free child, happy all day, and runs himself to death playing with other children so I don't understand where this is coming from. It's been going on for about 5 months now.
