For background, 2 years ago we lived in a 2 bed flat in which two of my children shared a room. We then moved to a large house with several rooms with a upstairs and downstairs and the kids don't share rooms. In fact they are on different floors, so this began the issue.
DC is 10 and worries about ghosts, they aren't allowed YouTube (they don't have safari etc etc) it's just stories or whatnot from friends.
They are on the stairs tonight refusing to go up until I go to bed.
On school nights this is a much bigger deal because they need to go to bed, and I refuse to go to bed at 9 each night, predicted by a child's fears.
As a child I clearly remember being in bed wide eyed, shitting myself, and unable to sleep.
BUT I didn't move house when we were 8.
