I have a 3 year old who goes to bed every night at 730pm. She's waking every night for hours on end. She is disrupting everyones sleep. I've found her in her brothers cot or under our bed. I've spend the last 2 hours awake. I can't figure out what's going on. Is it attention seeking? She doesn't seem to be having a nightmare. Has anyone experienced similar? She's also talking to herself - sounds like giving out to someone in school. Is it anxiety related. She's the middle child of 3 under 5 if that makes any difference?
