The cry of a thousand impatient kids in the back seat. mm are you one of them right now???
I dont know about the LRT in your sitch as it is . I would be rewarding good behaviour and ignoring the bad , not responding.
There have been some good things in your sitch and to respond with the LRT may just undo a lot of good. At least take 48hrs to think it over.
Have you had any DB coaching? , I know it is $$ but it may be a wise investment if you are lost in the way ahead. I am considering the option but being 1/2 a world away makes it a bit more difficult.
