For context, she's 9...she's bright, happy...popular at school etc so no worries there but she's always had issues with bedtime.
She seems to HATE being alone. She says she's scared and to be fair, she's never liked the dark.
She has dim lights...not bright enough to keep her awake etc...but she can't cope with being alone and always wants me or DH to sit by her bed.
Well that's a frigging NIGHTMARE>
I want an evening!
If we refuse, then she sobs....gets very upset.
So to try to make our lives easier, one of us sits by her bed till she's fallen asleep and it can take over an hour
I sit there SEETHING with resentment because she's NINE! It's been years now!
I just asked her if she could sleep alone with some low music on...she said she thought she could and said that she'd like Christmas music 
Shall I try it? What else can I do?
She's reasonable in every other aspect of her life...she's well behaved, eats healthily....gets TONNES of excerise daily...I feel like banging my head against a wall at times.
It's 8.00pm here in Oz and she's cleaning her teeth now.
