OK, Hilly, apology accepted :)
In another post you say "Statistics like '90% of mothers say they stopped before they wanted to' mean nothing whatsoever unless you expand on exactly what they said, and why they stopped."
Precisely, and you can judge for yourself if you find the Infant Feeding surveys, done every 5 years in the UK, independently (not by a 'pro bf organisation' at all, but commissioned by the UK health departments (all of them) and respected internationally).
Mothers consistently emerge with about 90 per cent of them who stopped in the first 6 weeks saying they stopped before they wanted to, and the ones who stopped before they wanted to are in a clear majority up to about 6 mths - you're right to say this is a bit bald, because they may have been really glad to stop if they were miserable bf.
In fact, the question asked is more nuanced than this. They are asked an open question 'why did you stop breastfeeding?' and there are about 10 reasons they give (it's not tick-boxy - these are open questions and the researchers then categorise them; no surprises there, it's stuff like sore nipples, not enough milk, baby feeding too often). One of the reasons is 'because I had breastfed for as long as I wanted to' and that's where the 90 per cent comes from - only 10 per cent give this answer.
Some survey answering is post-rationalisation - there's no recorded answer for 'my mother in law was hassling me' or 'my partner was jealous', just two reasons I occasionally hear from women who are having real wobbles about continuing. So no survey can tell the whole story.
It's also perfectly believeable that some women really did not want to bf for all that long, and give the reason 'not enough milk' and not 'because I had breastfed for as long as I wanted to' . But there's no arguement with the fact that many women do stop because of a poor experience, and would have liked to have had a better one.
