Tori, thanks for getting back to me. It's something that's close to my heart - I don't want anyone thinking they are damaging their baby psychologically with no reason!
"there have been studies on the effects of PND on infants and the failure to bond. If someone is so miserable that it is causing severe PND then they may fail to have a close bond with the baby. The exact opposite of what is meant to happen with breast feeding i.e. bring a mother and baby closer."
As I said to you, I know that the mother's psychological state affects her baby. That's a really serious thing, and can have long-term effects.
But it's difficult to quantify - I have supported many women who have not enjoyed breastfeeding, and are being made utterly miserable by it - but they do not want to stop! It may even be a factor in their PND, but stopping bf may make their PND even worse. It's a question of individuals working out what is best for them - they do not have to feel that hating breastfeeding and resenting their babies will damage their babies, as we have no evidence for that at all. Mothers can love and resent their babies at the same time, or resent them and still feel a huge sense of responsibility for them.
In some cases, the decision to stop bf for the sake of mental health could be the right one, but we can't make any generalisations...and that's what I was calling you on, especially as you implied it was a fact that resentment of bf causes PND, and there really isn't any research on this (as far as I know).
You have to be careful when you post here, sorry - don't say something as fact with no evidence to back it up
