Hi miss strawberry, I have just posted on your other thread.
I have read this book and found it helpful. Could I just say, don't read it all at once, read a chapter or half a chapter, live with that for a bit, then go back for more.
I found the most useful tip I got was the power of listening, without feeling that you have to fix anything.
So when they are bickering 'he said' 'she said' 'no I didn't' repeat ad nauseum, your job is not to fix them but to listen calmly to both sides of the story. You could then say something like 'well you both sound annoyed with each other, which is fine, but it is NOT okay to hurt each other's feelings however cross you may feel'.
Another thing I useful was how to validate their feelings.
Mum I hate Megan, she just annoys me so much, I don't want to play with her any more
My automatic response to anything negative was to reassure, make it all better eg. Oh Megan's not that bad, perhaps play another game with her etc etc.
But if you say Oh no, that sounds difficult for you, how are you going to deal with her tomorrow etc etc
It is much more helpful.
There is lots of good stuff in there, take your time and read it slowly.
