If you look at bf statistics, most women try to breastfeed and then for whatever reason, they stop. For most, this decision has come after a lot of anguish, soul-searching and guilt, and my experience is that as soon as I mention breastfeeding to anyone they will always remember that guilt and try to justify themselves by telling me what a horrible time they had and why they couldn't possibly carry on.
This means that throughout my life, whenever I have heard or spoken about breastfeeding, I've heard a negative story about how hellishly difficult it is. I was genuinely surprised to find that my boobs produced enough milk, that they stopped hurting, and that my nipples didn't fall off. I genuinely believe that with the right people with the right knowledge, the vast majority of women can breastfeed, but sadly that support is in shockingly short supply.
Read everything for yourself. Know everything. Don't trust ANYONE unless you know they have successfully breastfed themselves, and that includes doctors, midwives and health visitors. Go over to the MN Infant Feeding page and ask every question you have there. We live in a ridiculously breastfeeding unfriendly world, you have to be something of a maverick!
I'm lazy and not at all tough and I've been feeding non stop for six years over three kids. I've tandem fed and fed my first baby and fed a three year old, all of which people who should have been experts told me I could never do.
