I think as long as you are intelligent enough to discard the info that doesn't suit, there are some useful tips in the book....

I am one that would never use CC - I detest it and am very much against it, but I found a few tips useful to us - I now put DS in his sleeping bag during the day (as a sleep association) which worked for us, and I found her routines interesting, truthfully as a guide only, but I moved my DS's morning nap later like she suggested and it encouraged him to sleep in longer in the morning (instead of waking at 4-5am!!!)

I found Pinky McKays "Sleeping like a baby" suited my style perfectly! This one I would HIGHLY recommend

To anyone planning on reading it - my advice is to read with an open mind, and not to follow it to a T, its way to regimented and babies don't come from the same mould, they are all different, just like us adults are! So take what hints might work for you, and ditch the rest
