Might sound like a daft question but are they different from general bad dreams and what causes them?
My youngest has never been a great sleeper but in the last couple of months she seems to have gotten worse. Bedtime routine is good, usual bath/supper/quiet time/bedtime story then falls off to sleep no probs. But she does seem to cry a lot through her sleep. Some mornings she can even wake up quite early crying and moaning.
She is a very happy, confident child of 3 who is also very articulate for her age so able to talk about worries/fears etc. She is very bright tho with a vivid imagination. She just seems like a different child through the night. She can seem really upset in her sleep at times tho.
No major changes to her life, getting on great at nursery, like I said, really happy wee girl who is outgoing. Any suggestions as to what could be causing this?
