When my first baby recently turned 6 weeks it felt right to move away from rocking her to sleep all the time, and I also thought she wasn't getting enough sleep. Another problem was that I seemed to be feeding her pretty constantly from 5pm - midnight, with a couple of naps she'd have in my arms during that time (wouldn't go in her cradle).
I bought 'Sleep right, sleep tight' which was recommended by my pediatrician and while it had some helpful settling techniques, it didn't really help me very much.
My cousin (who has a 1 year old) gave me this book as a gift as she said it had really helped her. It's been just wonderful for us, with my little girl now seeming much happier, well fed and well rested.
The thing I like most about this book is that it isn't a book about settling her to sleep. It is a book that looks at a baby's whole day; when she should be feeding, playing, sleeping, burping, being warm enough in bed, the routine leading up to the 7pm bedtime etc etc. As a first time mum, I had no idea about any of these things, and in hindsight, I just couldn't tell the difference between her hungry and tired signs, or her different cries, so had real trouble with the whole demand feeding, more 'natural' approach. This book has taken the guesswork out of things and works really well for us. I also know when she is due for a next feed which is marvellous, as I can now leave the house when she is asleep and my hubby or mum is home minding her. Previously, I felt I couldn't do this as I didn't know whether she'd wake in 1 hour or 3 hours to demand a feed (and there was only so much breast milk I could express and have in the fridge in case this happened).
If someone had a lot of experience with babies, then this book probably doesn't help much, but I found it really helped me understand what my baby needs.
