Oh, I use it Lizzy - what that tends to do is act as a brake on her agitation building up to flash point. You hit a stage where whatever distraction/lwl/explanation you use, it gets mis-interpreted or twisted, and fuels her anger - no matter how nicely you speak, or how apologetic you are - and using that response then usually stops it moving to the point where she is pounding on doors or windows, shouting 'help me', and agitated enough to have us worried about her breathing. Sometimes, she will sulk when we say it, and then we get some peace. Sometimes, it actually stops her dead and she calms. Sometimes, not even that works. Sometimes, she keeps on trying to get what she wants or - it feels like - even provoke. Last night was the latter, but it still prevented the more extreme behaviour - she stayed stuck on the demands to be taken home, or be allowed to go to bed early (just can't let her - it always, always means a very disturbed night for us all) and was making odd nasty digs and comments , but went no further. I snapped when, after she had again said 'I'm going to bed now', and I'd again said 'You have to wait for your tablets at 10, and I am not discussing it again', then I went out onto the patio for a smoke and to take myself out of the conversation. She got up, said to youngest 'Well - I'm going so tell your Mum 'HA!', and headed up the stairs, meaning I had to come flying in and stop her. It must have been the 10th time at least it had happened, and this time, as I called her and asked her to come downstairs, she told me that I may as well forget having 'any peace' because she was going to 'keep this up' until I let her do as she wanted. All good resolutions flew out the window, and she got told in no uncertain terms exactly what I thought of her behaviour.
Stupid, stupid me, because it just made her all the more determined. I went back to 'Not discussing' afterwards, but now she had a 'reason' in her head to be justified in insulting me - and boy - did she! At 10, OH gave her her meds, and on her way through to bed, she stopped and made some comments along the lines of 'Got my own way', and like a fool, I told her to 'grow up!', and there was then an exchange of cross words as she left the room. I'm lucky that didn't start a full scale melt down, and could have kicked myself afterwards. But just sometimes, especially when you don't get 2 minutes peace in between her going on and on and on, I just struggle, and last night was one of those times
