NEWS NEWS NEWS NEWS: there is no breastfeeding mafia! There never was!
What there will always be is unsympathetic unkind unknowlegable ill-informed people who make comments or fail to help mothers about feeding.
There will always be people who put pressure on mothers to use formula when the mothers would prefer to hear other options if they have problems or for them to shut up about it if they have no problems.
There will always be people who are insensitive about a mother who is using formula and who comment on it, or who indicate some sort of judgment.
And there will always be women who feel emotional, defensive, disappointed, let down, unhappy in some way about their bf/ff feeding experience, because for many, it is more than just a way of getting milk into a baby, and it's part of their relationship with their baby and part of their identity as a mother.
For what it's worth, some of the examples here do not seem at all linked to any conspiracy or organisation.
The OP's midwife informed her she wasn't 'allowed' to recommend shields - this cannot be true, because midwives' practice is not regulated to that extent, but shields are not routinely recommended for sound reasons. I am not sure how that translates into 'mafia'.
Someone else had a family member, who was also an HCP, who made a silly and tactless comment about 'poison'.
Someone else had stupid and unkind office colleagues who were bossy to a pregnant woman.
Another person had a midwife who insisted on a lecture in the antenatal clinic which must have been boring, but surely no more harmful than that?
Point is - people say and do daft and unthinking things. Women may already feel these things deeply - and this is why daft and unthinking things shouldn't be said.
But claims about 'mafia' are neither funny nor remotely relevant.
