I've read the international edition, and it was so much about the US, and how systems worked there. In the beginning it was interesting, but then I started to realize that this is not applicable to where I inted to "work", (central and northern Europe).
There was also a lot about mothers, when they do this and when they do that, this happeneds to the child. Maybe a lot has happened in the field of equality and shared responsibilities of the upbringing and the responsibilities in the home (!!!) since the edition I read came out (10 years ago). Or maybe scientists have only studied mothers' interactions with their kids and are just moving in on exploring the fathers' part in the outcome of kids? Or maybe is it so much more common in the US that it is the mother who, in nearly all cases, is responsible for the home and to bring up kids. So, the book felt a bit unmodern, and not fully applicable to where I am heading.
