Some facts might help here.
Bf rates are rising in the UK and have been rising for 30 years.
It really does not matter if a midwife has bf or not. Experience without understanding can lead to incorrect advice - we see this every day on MN, with people using their own experience as a template for what others might do or even should do.
It's rarely possible to say for sure if an individual woman 'could have breastfed' if she had done/been told/tried x, or y, or z.
It's not possible to say how many women 'cannot' breastfeed. For example, we know it is vanishingly rare to produce no milk, but some women who have serious difficulty (for whatever reason) in producing sufficient milk choose to partially breastfeed. For another example, mother A might struggle for weeks in order to overcome an issue, whereas mother B might decide not to struggle as long because of other factors in her life, and mother C might stop after 6 hours because she is totally demoralised and scared, and mother D might stop after one feed because she was not very keen in the first place. In addition, reasons for not breastfeeding may be a mix of social, cultural, emotional, psychological, physical....there are hardly any cases where it is a clear cut issue of 'impossible' to breastfeed.
Even women who have no breasts can breastfeed - that is, give their baby milk at their breast. There is a case study on the web of a woman who did just this, using a supplementary nursing system....fiddly, awkward, at first, but this was something that mother wanted very much to do....of course not everyone would want to do that, nor should they be made to feel they 'ought' to want to do it, but it is an option and mothers in that situation should be made aware of it.
If a mother wants to breastfeed, there is therefore hardly ever any reason why she should not be enabled and supported to do so. Not one of the long list of reasons why a mother 'can't' breastfeed given by Juno stands up to scrutiny. This does not mean a mother with those circumstances should breastfeed - mothers should decide for themselves where their limits are.
There is no room for moral superiority, judgment, or outrage in any of this discussion. Or I wish there wasn't....
