I have read 'Best Feeding' but found it to be a little out of date. I'd recommend 'Breastfeeding ... naturally' which can be purchased through the Australian Breastfeeding Association (currently comes free when you join).

I have also found 'New Active Birth' and 'Waterbirth' by Janet Balaskas a good read, as well as 'The natural way to better birth and bonding' by Francesca Naish and Janette Roberts.

Depending on your mindset about pregnancy, birth and babies, be selective on what you read. Some books tend to scare you into a medically managed pregnancy and birth, whilst others are a little too free spirited in their guidance. You need to find the books that fit with your ideals on preganancy, birth and baby, and check that the author has reputable knowledge on what they are advising.
