Ds6 has suddenly started to have bad dreams. He's struggling to go to bed because he's worried about bad dreams and now he's awake because he's had a bad dream and can't go back to sleep. Ive been in and out to him for a hour and am now sitting by his bed. He just can't settle. He's got the light on. I'm out of ideas to help him and absolutely knackered. Any words of wisdom?
