This is going to be long and rambly...
DD is almost 9 years old and really struggles to get to sleep. Every single night, there is a battle to get her to sleep. This has been going on since June last year. I thought it was a phase but it's really starting to get me down. I get very frustrated and end up shouting sometimes 
It's not that she isn't tired. She's exhausted. She just fights sleep. Most nights go something like this....
Bed at 8pm. Read til 9pm then Lights out. Between 9-9.30 she will generally get up about 5 times (to go to the toilet, to get a drink, to check the time, to just get out of fucking bed to ensure she doesn't go to sleep
). She will then start calling me to tell me she can't get to sleep. I've tried cuddles and reassurance. I've got frustrated and shouted and told her NOT to leave her bed and to actually lie quietly without getting out of bed or calling me. I've tried rewarding her if we have a "good" bedtime (I.e one where she only calls once and is asleep before 10). I've tried punishing her (taking away screen time/pocket money) if she has a bad one. Nothing makes any difference. Bad nights mean her calling/coming in to me until gone midnight. 27 trips was I think about the worst!
I get no evening to myself. I usually have work to do after they're in bed but end up not being able to do much because I'm seeing to her. I rarely bother cooking anything because I'm always interrupted. And more importantly, she's fucking knackered. She has to be up at 7am on a school day.
She's an anxious child and I know getting frustrated doesn't help but it's so irritating when she wont even try to get to sleep. We've had so many conversations about it. It's like Groundhog Day. She is utterly obsessed with bedtime. Starts talking about it at around 5pm and seemingly spends hours checking the time and working out how many hours sleep she's had/will have.
Is it time for a GP visit or will I get laughed out of the surgery??
Sorry it's long. Any advice welcome
