I didn't mind 'Happiest Baby' - I watched the DVD and took a couple of tips from it. Kind of goes to why babies like to be held, rocked, cuddled while they're young and my DD really loved his 'head jiggling' technique and the swing we had for her (best way to get a proper shower!). Maybe I've forgotten, but I don't remember the DVD even mentioning a routine, it was mostly about settling.

But Pinky is excellent, so I'd go for her book first!
