My daughter for the past two years at least has been waking at night around 9pm to 10pm and through the whole night till about 5am some days. She wakes up either crying, talking rubbish, needing a wee or just shouting for either me or her dad but doesn't remember a thing the next day. We have tried waking her up to get her to snap out of it but she never seems to wake up completely. Any help would be much appreciated.
