alecia, please, please talk about your feelings with your supervisor or tutor, or whoever mentors the support group you trained with.
Of course you can't help your gut feellings - we all have those on various topics - but part of being a true supporter to other mothers is to have insight into our gut feelings, to understand where they come from, and in time, maybe to change them.
As soon as you go out into the world offering support to other mothers, you have to put your own feelings to one side, especially if they involve a judgement about other women's motives. I know you say you keep those feelings to yourself, but new mothers are very, very sensitive and they can smell bullshit even when there are no bulls around! You need to work on those very same feelings, and develop empathy and openness.
Keep the anger and the frustration, but don't direct it, even in your heart, at individual mothers. Instead, look at the terrible postnatal support women have; look at the commercial pressure and social pressure to keep mothers and babies apart and to buy a whole load of 'stuff' to make it easier; look at the f**d up attitudes women have to cope with...and above all, look at the fact that women have an individual right to do something you don't want to do with your children!
And yes, your attitude, and the attitude of cowardly name changer BreastIsBest, make my life more difficult. I'm at the sharp end, supporting and helping mothers every day, and telling people that support and help is non-judgemental, and no, we don't criticise mothers who formula feed, and yes, we understand all the complexities of infant feeding.....and then 2 posters like you come along and undermine it .
Do you understand why it's not good to express your feelings in this way? And alecia - will you seek out some further training, and take this thread with you?
There is nothing wrong at all with passion and strength of feeling. But with that, comes the responsibility to look at the wider picture and to rein yourself in, if necessary.
