MazStar, I also had a Contented Little Baby. But I think the book worked (WONDERFULLY) for us because DS, his father and even me, thrive in routines.
However I have also seen the damage that book can do to families not so suitable to those methods. My best friend loathes the book and says she is convinced that book landed her in deep depression. That book kept my sanity while dealing with a sickly baby with no support whatsoever apart of that of my then husband. I know both my friend and I are right.
All my respect for GF died on the days I saw her around here, she was such a fundamentalist bully I thought it was a troll pretending to be her. I was in those threads were she acted like a mad woman because people disagreed with her.
It was not until she threatened MN that I realised that the dear unpleasant troll was no one but herself.
When she had the problem with MN, Mumsnet was still a relatively small web site relying on good will donations from its members, and there was a real danger for it to shut. Thankfully it didn't. Actually, someway I think GF contributed like no one else to the success of Mumsnet. We were all so horrified at the thought of MN closing that one way or another we were in the national news before the end of the day, and soooo many people (between them plenty of ad paying people) realised the potential Mumsnet had, therefore bringing a lot of new users and a lot of advertisements that helped Mumsnet to survive and prosper to what it is today.
... Or at least that was my take on all that
