I had the exact same thing happen to me - I told the midwives I hoped to all things going well. The lectures began, although I didn't have the history you have.
As it turns out, I'm a regular old cow (in more ways than one....) but I am lucky, and there are alot of people that can't do it - for whatever reason. The girl next to me in hospital didn't want to because "it made her feel sick". I reckon that is a crap excuse, but at the end of the day, it was her decision, and the midwives let her make it! There were heaps of women bottle feeding in hospital - I saw at least 8 different women making up bottles when I was in, and there are probably only 16-20 mothers in hossy at any one time??

As for bfding - as the others have said, I have heard conflicting info from every midwife I have seen. Take the good bits, ignore the rest of the crap cause it just makes you doubt yourself. As long as your baby is healthy and putting on weight, and you are doing OK, thats all that matters at the end of the day.

Good luck
