When a woman is struggling with breastfeeding, and she asks for help from someone like me (NCT breastfeeding counsellor, probably someone like you saw, fizz, that is - we are asked by the mother herself for help) then it is reasonable for us to assume the mother does want to breastfeed.
We do, sometimes, check this, as her view might change, or she may just be exploring options and want to assess how much more she has to struggle in order to bf...and we might well ask in a kind and polite way if she wants to breastfeed.
I don't think we would say 'do you want to breastfeed?' in a sort of eye rolling impatient way, but I would prob say, 'can I just check your feelings on this, if you're still planning to carry on breastfeeding....?'
This allows her to be open about her ambivalence (and she often is ambivalent) and to discuss maybe carrying on with some breastfeeding, or gradually switching to formula or whatever, and I will (of course) help her with all of that.
It is not intended to be a guilt-inducing or pressuring question, or meant to make anyone 'feel selfish'.
Asking the question in a way that leaves an exhausted mother 'unable to articulate' how she felt is just crappy care, I think, but it is the mother's responsibility to be open with her carers and counsellors and accept they may be as sensitive as, um, a very sensitive thing, but that not all of them will be mind-readers
This is not to be critical of your comments, fiz, which are valid and I think reflect a not-uncommon situation. Not sure what the answer is!
