9-Year Old with Sleep Issues

I have a little one around same age who has recently had a bout of anxiety. Sometimes it rears it's head at bedtime. Typical I think for anxiety.

For us, allowing her to regress a bit has helped. So we went back to reading to her at bedtime - some of the stories are younger. I also found it extremely helpful to move bedtime ahead by a lot. Sometimes 1/2 hour to a whole hour ahead. So we're reading now way earlier - and we took away electronics after dinner altogether. I don't know if that was part of it - she's never been a big one for them, but I think it can stress some kids out.

If it were me, I would read to your child, in her bed. Maybe get her a new comforter, stuffy, new light, whatever to make room inviting again (transition age as tween) start new routine in there. Read till she's drowsy. Say you will each stay until she's drifting off (or asleep - whatever works). I'd do that for a week. From then on say you will come up and check on her until she is asleep for a week. Do baby steps.

Good luck and keep us posted :)

When my daughter went through this, one thing that helped to set a rule/boundary was that I would lay with her for three songs (we had on a radio for background noise), then after a week or so, it decreased to two songs, then one. This was actually when she was still in her own bed in her room. If she was still awake and nervous, she could come "make her nest" on the floor of our room. Once we were done laying down with her (to keep her comfy there in the first place), we'd kind of count up: "I'll set the time for 2 minutes, if you're still awake, you can come into our room." Then it moved to 5 minutes, then 10, so she'd have more time to relax and go to sleep. But she was comforted, knowing that she could come in if she needed to, after a certain time. I guess that's two scenarios, hope it's not too confusing.
It's a really common phase to go though, you're not alone.

Make bedtime a routine, no electronics at least one hour before bedtime and, as your plan, make a chart with bedtime for school/weekend nights and consequences (be consistent with these).
Maybe a warm shower could help her to relax, and reading before light-off.

Try a trip to the bookstore for some interesting new books for "before bed" only. Have her go to bed a little earlier for reading time. Is her room near a family area? Have her leave her door open and if possible stay near by her room so she can relax and not feel so alone. My kids rooms are on the main floor. I used to be close by in the kitchen so they could hear me cleaning up a bit when they were getting ready to go to sleep. Also white noise is good. The dishwasher worked for us. Even a TV playing softly in another room might help.

Another thing I swear is the best at inducing a good night's sleep is swimming in the afternoon or evening. If you have a place to do that, I'd give it a try as a family activity.

And also try to wake her up the same time on the weekends as she gets up during the week

Tough situation.
Everyone needs to sleep - and your daughter has anxiety about it.
Maybe a counselor could help her with some relaxation techniques.

Is there room for a chair in her room?
A first step is getting over someone laying with her while she falls asleep.
A teddy bear can take your place.
You or dad should be able to sit nearby while she falls asleep - and then gradually shift the chair further away and eventually out the door as she gets more comfortable with falling asleep on her own.

A calendar I guess is useful to have a schedule and to get things written out.
Bedtime rules and consequences should become second nature as the routine is followed night after night without variation.
