Try some deep pressure before bed. Either sit with her on your lap facing away from you and give her a strong hug while rocking. This can calm an overactive nervous system. Also the usual, calm enviroment--- soft light, warm bath, etc. You can also set up her bed to be nest like---- lots of stuffed animals around her. Sounds strange but my son had an issue calming enough to sleep and they suggested this. Shorten her nap if she still takes one and make sure it isn't too late in day. My son has sensory integration disorder and kids with this can have trouble sleeping sometimes because their nervous system is very active. Good luck and after the 9th, you'll know more to help her.
i tried all that stuff before, but one thing i noticed her, but it seems that in her mind something bother her, even in the day time she play for example and then all of the sudden she will set down and seems to me she try to remember something and then she will start to cry. and i dont remember that she had a bad experiece or bad thing happened to her. she has a 4 yr old sister w/c is very loving, understanding. during the day time she has some favorite chair full of stuff toys but she doesnt like the stuff toys to be w/ her on her bed. special mom, thanks for your advice..
When you have a developmental evaluation---- talk to them about her sleeping issues. they can be common with delays and specific to a child. Our occupational therapist came up with those suggestions for our son when he was going through a period and for our son they worked. Whoever is helping you with your child should also be able to help you problem solve with your daughter. Good luck as a good night sleep is so important!
