Seems like this new book is causing some commotion at the moment - just read this article in The Local.
I can't really decide if I agree with it totally, but I do have the view that disciplining children and setting boundaries allows them to feel secure and to know what to expect.  Which helps make things like eating out, going to the supermarket, sleep time and socialising that bit easier.  In Sweden discipline doesn't seem to be a priority and I don't know any Swedes who give their children consequences for their bad behavior, that only comes from my non-Swedish friends!  And manners, well don't get me started!  Whatever your view, it makes for a good read me thinks!
