I saw a doco on the author and her book, whilst in the UK. From what I saw, it didn't look like something that would work for me. But it was interesting, because they had a few couples try to follow her routines. From memory, some found that it worked really well, probably because it suited their and their children's personalities. Those for whom it didn't work, ended up feeling stressed, depressed, and as though they had failed... particularly if they tried to follow it exactly.

Poor old Gina Ford... some love her, but many hate her.
