I must agree with others, I didn't read any books and I BF DD for 10 months (I only intended on 4 months). Can you do NCT classes? They have a very helpful session just on breastfeeding. Also, do you know anyone who has successfully breastfed in the past? I had one of my best friends who was a star, and had a very frank chat with me about what to expect, and was a great support in those early difficult days.
The BF forum on here is also very helpful for support xx
