Gosh, the poor girl! It must frustrate her as well, I'm sure.
My girl is only 6 years old, but I have found that at bedtime she gets so wound up, because she has a lot of stuff to unwind about... the whole day! So, before bedtime, we sit together... (she likes to chat and cuddle), and I just let her talk story and "connect" with me and we just hang out/talk/chit chat/ do girl talk etc. and then this seems to "relax" her. Then she seems less pent up or tense. I also sometimes give my girl a back massage... and this really helps her to unwind.
My girl is just very cerebral & imaginative... and she just has a hard time shutting off her brain....or she will go on and on and on just wanting to talk and think and she can talk forever! Or yes, we read a book.
There is also something called "Hyland's Calms Forte" (kids or adult versions) which is a homeopathic alternative and has no contraindications and is not habit forming. Lots of adults or kids use it when traveling etc. or to aide in calming. Being that it is homeopathic, it will either work or it won't. Some adults take it for stress or insomnia too. Anyway, I have used it when my kids were teething and it seemed to help. My friend uses it when they travel, because they travel a lot, and she said it helps her kids. That is how I learned about it. And no, it is NOT a "tranquilizer" or sleep aide..
Or, the brand "Animal Parade" makes something called "Animal Parade Warm Milk" supplements. It is to help kids relax and sleep better. The main ingredient being magnesium. From what I gather, per the Owner of the natural food store I go to... "magnesium" can really help relieve stress and help to calm and sleep, in some people.
Also though, is your daughter perhaps eating anything that may contain caffeine? Young kids nowadays seem to be eating/drinking things that are caffeinated... (I read about it in the newspaper recently), and unbeknownst to Parents, this is getting them too "wired" and causing problems.
Perhaps also, she is at the age where developmentally they are changing so much... maybe this can cause a problem with sleep....just as would happen in babies. ???
All the best, just some ideas & natural products, hope it helps,
Susan
