"that the bf was only one part of the child's experience"
Well I agree with you, and nothing I said suggested that I see bf as the 'only' important thing. That said - tiny babies do little other than sleep and feed, and to a very large extent their relationship with their mother is mediated through the experience of breastfeeding.
"and that the emotional welfare of the mother is not a separate issue from that of the child but the key element of the child's experience and life quality as a being totally dependent upon her and therefore her well being and state of mind."
Yes - I agree with this also, that you have to see mother and baby as a unit. But I don't think that the usual discussions about feeding choices generally do this, other than to pay lip service to the idea of 'happy mother happy baby'. From where I'm standing the usual argument seems to go like this: breastfeeding is really hard, and if a mother doesn't like it or struggles with it then it's better for her and her baby if she doesn't do it.
But bf is especially hard for women who are given crap care, and for women who come from communities where bf is not the norm. Does this mean that all those mothers are REALLY better off not breastfeeding and their babies are really better off without their mothers' milk? It seems all wrong to me to arrive at that sort of conclusion, when we know that unproblematic breastfeeding is linked to better mental and physical health in both mothers and babies. We should be asking the question: why is breastfeeding so much harder for some women than for others? and why are social class, education, age and ethnicity the predominant factors when it comes to the likelyhood of someone choosing to breastfeed, or to continuing to breastfeed as long as they wish?
Finally - I do agree about the importance of networks of support for mothers in different communities. However, as I think that unproblematic bf is actually less onorous and less stressful for women than normal bottlefeeding, I don't think that high bf rates are reliant on mothers having a highly developed network of support within the family. I live in an area where there are lots of immigrant women who are separated from wider family support, and we have incredibly high rates of bf. This is despite the fact that many of these women have large families with close age spacings, and often live in quite poor housing. They breastfeed because - well, it's just part of what they see as the normal picture of being a mum. Most other women in this country simply don't see it in that way.
