My son at times exhibits basics levels of anxiety which I have not seen in most of the other children. I did not have enough time to go through the entire book and read it thoroughly. So I skimmed through the pages and tried to do things that seemed relevant to us.
But none of them seemed to do anything helpful practically. My son could never do what was mentioned and after trying for some time, I too did not care about it.
I also found the advices to be used in extreme cases and my son I think was not that extreme a case.
