I doubt this thread will go poof, Gina Ford is not a banned name anymore.
I used her with both of mine. For me it worked. I was a first time mum with dd, I didn't have the first clue about babies and it wasn't as if I was getting any kind of constructive advice from anyone. My life revolved around dd sleeping and waking and I was in a constant state of exhaustion.
I liked Ford's routines. For once the day started to slot into place and I started to feel a little more in control.
I liked that I did things at certain times. For me that was comforting and it restored order to a chaotic house.
dd soon settled into the routine and so I finally started to have hours of unbroken sleep at night which helped me to feel whole again. I could cope better because I was less tired, I had a routine to follow and I felt in control.
The afternoon nap also gave me the freedom of a couple of hours to do what I wanted to do. Whether that was to go shopping with her in the pram, to read a book, do the housework, whatever.
I can understand that some people hated it precisely because the routine was so rigid, but that's exactly the reason I liked it. Once I started to feel more confident about being a mum, I found I could tailor the routine to fit around our lives a little more.
ds didn't take to it in quite the same way but still the night times were better and I still got my couple of hours in the afternoon.
I think if you are a fan of the Baby Whisperer and want to follow your baby's lead in everything or you already have a good idea of what you are doing, then the book is not for you. But if, like me, you are feeling out of your depth and just wish you could hire a nanny to sort it all out for you then it's invaluable.
The OP sounds like she has it pretty much sorted anyway so she might take some things out of it and she might not.
I would never completely trash a book because you might just be dissuading someone to try something that could completely change their lives (and following that book more or less did that for me).
It's rather selfish to tell people to bin a book based purely on the fact that you did not like it. I would tell them why it didn't work for me and would advise that they try it.
