Yes. I borrowed a copy from the library last time and intend to read it again before this baby comes.
I used the routines on Michaela who at 10mo still hadn't sleep through the night and was still waking for 2-3 (comfort) feeds every night. Using the routines combined with advice from friends, family and The Sleep Store (and most importantly doing what I felt comfortable with) my daughter started sleeping through the night every night and was heaps easier to put down to sleep for her day naps and night time sleep.
