Tizzie Hall is a bit strict for me. Some of her ideas may and I say may work. Have a GF doing it and it seems to be working for her, well sort of.
On saying that I let my DD do what she wants with feeds and sleeps during the day as she is sleeping all night without any tears when she goes down, could be just her though, she is a very easy going little girl
I am big fan of Robyn Barker, she is pretty practcial in her approach to all things baby, breastfeeding and so on.

Good luck...you will get your own rythym. If you are interested in having a read of Save our Sleep I would reccommend trying to borrow it out of your local library before purchasing it.
