I can understand exactly how you are feeling, I have been told by friends that I should just leave her to scream. I can't. She has eczema and will just rip at herself or make herself sick, sometimes its like she changes into another person screaming etc. Its so not nice.
Our house is pretty relaxed and happy during the day and my kids are really well behaved (I think anyway) but as soon as its bedtime it all changes. We have never brought her into our room, a few years ago I used to sleep on her floor (mad I know!!!) and reward charts are the same for us too she gets bored with them. Last night she did sleep but it took her ages to settle, I worry the most about her school work as her teacher has said that she is exhausted.
I took her to the docs a while ago as she would not get changed at gym and was being a real pain and I got really cross, it was so not me but the lack of sleep drove me to be a cow. The doc was great and gave us some antihistamine for her eczema which should make her drowsy, that did work for a while but I really don't like the idea of her taking meds to help her sleep.
I have a whole library of 'how to get your child to sleep' books. We are moving soon and hopefully can borrow enough cash to build another room onto the house so then she will have her own room, I don't know if that will help, but at least her sister will get some peace.
Can you get a break at all and let someone else sort him out? My parents have been really good and had her for the occasional night - she is really bad when she comes home tho, but at least I have had some sleep and can cope with her.
Go on as much as you like, I don't think people can understand just how exhausting it is not to get sleep. you can't function and its make you feel so ill. It is nice to chat to someone who is experiencing the same problem as me, if I talk to people they either think I am exaggerating or lying. It might help to put your feelings down, it has me.
Here's to a good night tonight
