No I do understand bumbleweed - I understand what you have said, and I understand your ambivalence about what you want and what you feel is right.
"In terms of having to accept some crying - my position is that crying without us right next to her defo out, crying in our arms not nice but tolerable - often happens when dh's turn to settle her to sleep but only crying about 10 mins."
I agree with what you have said here, bumbleweed. There is no need to leave a baby on their own crying, in order for them to get to sleep. There is no need for her to learn to go to sleep by herself at this age - why should she? I disagree with virtually everything you have said, sparklemagic.
"To be kindest to HER she needs her parents to show her what bedtime is and how it is done"
No, she needs her parents to respond sensitively to her needs, as they have been doing
"you can relax about feeding her in the night - she doesn't physically need this"
Have you got proof for this, or just a childcare guru's opinion? How do you know what bumbleweed's dd needs physically?
"the fact that her being with you and 'on' you etc is actually stimulating her and keeping her awake"
This is not a "fact", this is just more Baby Whisperer opinion, isn't it?
Erm, sorry, bumbleweed, us disagreeing about what to do is not helping much, is it?
I am a bit stumped as to what to advise, as I have never been in this exact situation myself. The ring sling could work for you as suggested earlier, or you could perhaps try lying down together, with you patting her, or you could try the methods described in the No Cry Sleep Solution book (very very gentle child-centred sleep training). We co-slept which certainly simplified matters a lot - he never had to learn to be in his cot, and I never had to get up to feed in the night, just fed him lying down (still half asleep when he was little).
There is absolutely no need to either night wean her, teach her to sleep in her cot, or to teach her to fall alseep by herself, unless you personally want and need her to do any of those things. There is nothing wrong with letting her fall asleep with you there, or feeding her to sleep, or co-sleeping with her, or feeding her in the night. My ds has recently weaned himself from all of the above at the age of 3, with very little upset. He has always been a poor sleeper and never had as much sleep at night as many of his peers, yet he is a tall and healthy child who is obviously happy and intelligent. I don't think getting less sleep than I may have liked him to have in an ideal world has damaged him in any way.
You might also like to do some reading on the Dr Sears site (if you must recommend gurus, people, at least choose one whose basic philosophy is in line with the poster's own outlook on life). this page is very helpful, I think.
I wish I could be more helpful but at least you can come here for sympathy - it is lovely to see how mnay people have posted here to try and help (even if I don't agree with what they say )
