My 6 year old son has started waking up quite often during the night. He always starts crying horribly and talking about random things. But he's still asleep. i ask him in the morning if he remembers but he doesn't. This gets so wearing for me, having to wake up early for work on 8 hours of completed interupted sleep :( Not to mention he's not getting a good nights rest. Has anyone else ever experienced this with their children?
